Theresa May has praised women who had the “courage” to report allegations of sexual harassment by Hollywood producer Harvey Weinstein, raising the prospect he could be stripped of his honour.

The Prime Minister said that “unwanted sexual activity” is unacceptable and called for all the allegations against the movie mogul to be fully investigated.

Barack and Michelle Obama are among the other high-profile political figures to have condemned the allegations, saying that they were “disgusted” by the reports.

A number of senior Labour politicians have also signed a letter to Ms May calling for Weinstein to be stripped of his CBE.

Speaking as the furore over the Weinstein allegations grew, Ms May’s spokesman said: “The reports over the recent days are deeply concerning. Any unwanted sexual activity is completely unacceptable.

“Any allegation should be fully investigated. Anyone who comes forward to report these kind of allegations should be praised for their courage.

Weinstein was protected by 'machine designed to keep claims quiet

“The independent Honours Forfeiture Committee considers cases where the honours system has been brought into disrepute, their discussions are confidential. It’s right that we let them get on with their work.”

An open letter to the Prime Minister has been signed by Labour frontbenchers Chi Onwurah, Jack Dromey, Dawn Butler and Kevin Brennan and the head of the Women’s Parliamentary Labour Party, Jess Phillips, describing Weinstein’s alleged behaviour as “unacceptable and intolerable”.

Harvey Weinstein: his accusers Show all 42 1 /42 Harvey Weinstein: his accusers Harvey Weinstein: his accusers Harvey Weinstein Harry Weinstein’s reputation as one of Hollywood’s leading executives was long cemented in stone. The acclaimed movie mogul, who produced Oscar-winning films Shakespeare in Love, The English Patient, and The Artist, clocked up box office successes and accolades aplenty. But this has quickly changed since a chorus of women have come forward to accuse the Hollywood producer of sexual harassment and assault. Since the New York Times’ bombshell report disclosed sexual harassment and rape allegations against the film mogul dating back decades, Weinstein has been fired from his namesake company, expelled from the Oscars and has had his wife leave him. Weinstein has apologised for having “caused a lot of pain” but has denied all allegations of nonconsensual sex. Getty Harvey Weinstein: his accusers Annabella Sciorra The Sopranos actor alleged Weinstein raped her after shooting The Night We Never Met, a 1993 movie that Weinstein produced. Similar to the stories told by other women, Weinstein drove the actor home, only to reportedly burst into Sciorra's apartment and start unbuttoning his shirt. “He shoved me onto the bed, and he got on top of me,” Sciorra said. “I kicked and I yelled.” Weinstein then allegedly locked her arms and forced sexual intercourse on her. After the incident, Sciorra found it increasingly hard to get work, many filmmakers saying 'We heard you were difficult', something the actor claims was because of the 'Weinstein-machine'. Getty Harvey Weinstein: his accusers Natassia Malthe The model and actress, who has appeared in around 50 films, said she met Weinstein at a BAFTA after party in 2008 while she was working as a spokeswoman for LG. She told a press conference in New York that she felt pressured into telling Weinstein she was staying at the Sanderson Hotel after being put on the spot. Malthe, now 43, said after her shift on February 10 she went back to her room and went to sleep, but was awoken by "repeated pounding" on her door, from someone yelling: "Open the door Natassia Malthe, it's Harvey Weinstein." Feeling humiliated, she said she opened the door. She alleged Weinstein began implying sex would get her a role in an upcoming film while semi-undressed and then he began to masturbate. "I was sitting on the bed talking to Harvey when he pushed me back and forced himself onto me. It was not consensual. He did not use a condom," she said. AP Harvey Weinstein: his accusers Sean Young The actor, best known for her role in Ridley Scott's Blade Runner, said that Weinstein exposed himself to her in the early 1990s, when she was starring in the Miramax-produced Love Crimes - a production company that Weinstein headed at the time. "I personally experienced him pulling his you-know-what out of his pants to shock me," she said. "My basic response was, 'You know, Harvey, I really don’t think you should be pulling that thing out, it’s not very pretty.'" Young never worked with Weinstein again after the incident. Harvey Weinstein: his accusers Mimi Haleyi Mimi Haleyi said she was assaulted by Weinstein in what appeared to be a child's bedroom in his New York City apartment in 2006 when she was in her 20s. She said she was aspiring to work in television and film production when she was first introduced to him at the London premiere of The Aviator around two years earlier and he helped her get experience on the set of a TV show being produced by The Weinstein Company. But, she added, he repeatedly hassled her and even tried to force himself through her front door in an effort to get her to join him on a trip to Paris. At one point he allegedly forcibly performed oral sex on an aspiring production assistant while she was on her period. Getty Harvey Weinstein: his accusers Lupita Nyong'o In an op-ed for The New York Times, the Oscar-winning actor said she was invited to Weinstein’s family home in Connecticut on the premise of watching a film shortly after they met in 2011. But she said shortly after it started he "insisted" in front of his children that she follow him and she was led to his bedroom. The Kenyan-Mexican actress, now 34, said she felt pressured into giving him a massage after he offered her one. "Before long he said he wanted to take off his pants," she wrote."I told him not to do that and informed him that it would make me extremely uncomfortable. He got up anyway to do so and I headed for the door, saying that I was not at all comfortable with that." Over the years that followed, he continued to get in touch, Nyong'o said, and when she declined another proposition she felt her career was threatened. Getty Harvey Weinstein: his accusers Lena Headey Writing on social media, the Game of Thrones actor claims she first met Weinstein at the Venice Film Festival in 2005 where, after taking her for a walk by the water, he “made some suggestive comment and gesture.” Headey claims she bumped into Weinstein years later where he kept asking her questions about her love life. She alleges that, when Weinstein invited her to his hotel room to show her a script, the "energy shifted.” The actor notes how, after saying she was not interesting in anything but the work, Weinstein was furious, apparently marching her back to a lift, "grabbing and holding tightly to the back of [her] arm." She claims that, after paying for her car, he whispered in her ear: "Don't tell anyone about this, not your manager, not your agent.” Headey finished the post, writing: “I got in the car and I cried.” Getty Images Harvey Weinstein: his accusers Lucia Evans The actor told The New Yorker that after a meeting to discuss casting her in various projects, Weinstein forced her to perform oral sex on him. “I said, over and over, ‘I don’t want to do this, stop, don’t’.” She added: “He’s a big guy. He overpowered me. I just sort of gave up. That’s the most horrible part of it, and that’s why he’s been able to do this for so long to so many women: people give up, and then they feel like it’s their fault.” Getty Harvey Weinstein: his accusers Laura Madden Madden, a production assistant who worked at Miramax for a decade, told the Times that Weinstein allegedly “prodded her for massages at hotels,” a common theme among the sources the Times’s reporters spoke with. On one occasion, she claims she locked herself in his hotel bathroom, sobbing Harvey Weinstein: his accusers Ashley Judd Judd recounted for the Times how Weinstein allegedly harassed her while she was filming Kiss the Girls in 1996, inviting her to his hotel room and asking her for a massage, then inviting her to watch him shower. Judd first went public with the allegations in a 2015 interview with Variety during which she discussed the experience without naming the producer involved. She described Weinstein’s alleged behaviour as “coercive bargaining”; “I said no, a lot of ways, a lot of times, and he always came back at me with some new ask,” she told the Times AFP/Getty Harvey Weinstein: his accusers Rose McGowan McGowan reportedly reached a “previously undisclosed” $100,000 settlement with Weinstein in 1997, over an incident that occurred in a hotel room Getty Harvey Weinstein: his accusers Mimi Haleyi Mimi Haleyi said she was assaulted by Weinstein in what appeared to be a child's bedroom in his New York City apartment in 2006 when she was in her 20s.

Getty Harvey Weinstein: his accusers Emily Nestor Nestor had been temping at the Weinstein Company for only one day in 2014 when Weinstein allegedly offered to boost her career in return for sexual favours, according to the Times. She declined and reportedly complained of his behaviour to colleagues, who later passed the information on to senior executives. An internal Weinstein Company document cited by the Times describes Nestor’s encounter with Weinstein as follows: “She said he was very persistent and focused though she kept saying no for over an hour” Getty Harvey Weinstein: his accusers Ambra Battilana In March 2015, Battilana, an aspiring model and actress, was reportedly summoned to Weinstein’s office on a Friday night to discuss her career. According to a police report cited by the Times, Battilana claimed she was assaulted by Weinstein, who “grabbed her breasts after asking if they were real and put his hands up her skirt.” Weinstein later claimed that Battilana had set him up, according to colleagues of his who were interviewed by the Times. The Manhattan District Attorney, Cyrus Vance, later declined to press charges, and according to the Times, “made a payment” to Battilana. On 5 October, the International Business Times reported that after Vance dropped the charges, he received $10,000 from Weinstein’s lawyer Harvey Weinstein: his accusers Lauren O’Connor Lauren O’Connor, an employee of the Weinstein Company, penned a memo to executives alleging “a toxic environment for women” at the company. The memo cited numerous incidents of Weinstein harassing or coercing women who worked for him. She expressed fear that Weinstein was using her and other female employees to “facilitate liaisons with ‘vulnerable women who hope he will get them work.’” That same year, Weinstein allegedly reached a settlement with O’Connor Getty Harvey Weinstein: his accusers Kate Beckinsale The actor, who starred in the Weinstein Company films Serendipity and The Aviator, alleges that she was invited to Weinstein’s hotel room at the age of just 17. When she approached the door, the producer reportedly greeted her dressed in just a dressing gown. “I was incredibly naive and young and it did not cross my mind that this older, unattractive man would expect me to have any sexual interest in him,” she wrote on Instagram. “After declining alcohol and announcing that I had school in the morning I left, uneasy but unscathed.” Theo Wargo/Getty Images Harvey Weinstein: his accusers Gwyneth Paltrow The actor alleges that after he cast her in the title role of the film Emma when she was 22, he took her to his hotel room, placed his hands on her and suggested massages. “I was a kid, I was signed up, I was petrified,” Paltrow told the New York Times.

When she was initially invited to a meeting with Weinstein, Judd said, she was surprised to learn the producer was in his hotel room - a tactic that recurs in other womens’ accounts. Echoing the accounts of other women, Judd said Weinstein suggested she give him a massage and then invited her to watch him shower. After a “volley of no’s” she said she would only after she wins an Oscar, fleeing after making the comments.

Rex Features Harvey Weinstein: his accusers Katherine Kendall The actress said Weinstein undressed and chased her around a living room when she was just 23.

Very inappropriate.” Getty Harvey Weinstein: his accusers Lysette Anthony Lysette Anthony, who starred as Marnie Nightingale in Hollyoaks, has claimed Weinstein raped her in the late 1980's after turning up to her London home in the late 1980’s.

Rex Features Harvey Weinstein: his accusers Louise Godbold Writing in a blog post, Louise Godbold, a non-profit director in Los Angeles, said her encounter with Weinstein took the form of an “office tour that became an occasion to trap me in an empty meeting room. She said then Weinstein was “begging for a massage, his hands on my shoulders as I attempted to beat a retreat.”

The letter goes on to say that keeping his honorary CBE in place risks “bringing the honours system into disrepute”.

Weinstein has rejected many of the allegations and issued a vehement denial over three allegations of rape which emerged on Tuesday.

But the wife of the disgraced Hollywood producer, fashion designer Georgina Chapman, still described her husband’s behaviour as “unforgivable” and announced she is leaving him.

In a further development on Wednesday, the British Academy of Film and Television Arts (Bafta) suspended Weinstein’s membership from the organisation.

The body said: “Whilst Bafta has previously been a beneficiary of Mr Weinstein’s support for its charitable work, it considers the reported alleged behaviour completely unacceptable and incompatible with Bafta’s values.”

On Tuesday Gwyneth Paltrow and Angelina Jolie joined a growing list of stars making claims about the producer, which has seen him dismissed from the company he co-founded.

Speaking to The New York Times, Paltrow claimed Weinstein summoned her to his suite at a Beverly Hills hotel after he had hired her as a lead for 1996 hit Emma. She said he placed his hands on her and suggested they head to the bedroom for massages.

“I thought he was going to fire me,” Paltrow told the publication.

Pulp Fiction star Rosanna Arquette and French actress Judith Godreche made similar accusations, while Jolie said he made unwanted advances on her in a hotel room.

The Obamas said in a statement: “Any man who demeans and degrades women in such fashion needs to be condemned and held accountable, regardless of wealth or status.”

Weinstein had issued an apology for his behaviour prior to the rape allegations surfacing, saying he appreciated that the way he had behaved with colleagues in the past “caused a lot of pain” and that he realised he “needed to be a better person”.
