Protesters today vowed to disrupt Donald Trump's visit to Britain on July 13 with mas protests.

The US President will come to the UK for talks with Theresa May after travelling to Europe for a NATO summit.

The confirmation of the working trip - which will not have all the pomp and ceremony of a state visit - comes after months of difficult wrangling between the White House and Downing Street over the plans.

But it sparked immediate threats of protest as activists said they would 'take to the streets' to vent their fury at his visit.

Jeremy Corbyn-backing activist and commentator Owen Jones took to Facebook to urge Britons to join mass demonstrations against the visit.

Writing on the 'Protest Trump's Visit' Facebook group - which has over 100,000 people interested in it, he wrote: 'It's official; Donald Trump is visiting the UK on 13th July.

'Everyone out on the streets! Invite everyone you know to this event.'

Police have been bracing themselves for what could be the biggest protests the country has seen.

And the Lib Dems vowed to join the demonstrations, with their deputy party leader Jo Swinson saying: 'The Government has made the right decision to cancel Trump's state visit, but this scaled down trip must not be met with scaled down protests.

'Protesting against a man with dangerous, misogynistic and racist views is our responsibility.

'It is our opportunity to stand in solidarity with all the people he has abused and denigrated.

'When he comes to the UK the Liberal Democrats will be front and centre of the protests.'

Announcing the visit today, the PM's spokesman said this evening: 'The President of the United States will visit the UK on July 13.

'He will hold bilateral talks with the Prime Minister during his visit. Further details will be set out in due course.'

The Foreign Secretary tweeted his delight at the news that the visit will final take place after many months of speculation

London mayor Sadiq Khan - who has a long-running spat with Donald Trump - said the US President will be welcomed and seen Britain's 'liberal values of freedom'

Ministers will be hoping that the fact Mr Trump is coming on Friday 13th is not an unlucky omen.

Boris Johnson tweeted his excitement at the visit, writing: 'Fantastic news that President Donald Trump will at last come to Britain on 13 July. Looking forward to seeing our closest ally and friend on the greatest visit ever.'

The details of the itinerary for the trip have yet to be released.

There has been speculation that the talks with Mrs May will take place at her Chequers country retreat rather than Downing Street.

Mr Trump could also meet the Queen or other senior members of the Royal Family, even though it is not a state visit.

Officials will be keen to roll out the red carpet while also minimising the prospect of protests.

The President is expected to attend the Nato summit in Brussels on July 11 and 12 and travel on to the UK afterwards.

There had been speculation that the prospect of mass protests on the streets might scupper the idea (file image of a demo against Trump in 2016)

Some Tory MPs were jubilant at the news. Backbencher Nigel Evans told MailOnline: 'I am really pleased he is coming particularly so soon after Macron's red carpet treatment in Washington.

'We should never take the Special Relationship for granted. We know the Left are going to be fuming that he is coming to the UK.

'It is pathetic. The fact is that these are the same people who cheered Obama when he said before the EU referendum that we would be at the back of the queue for a trade deal.

'Trump is a man who loves the UK.'

In a sign of the stormy reception Mr Trump could face, Amnesty International spokeswoman Kate Allen said: 'When Donald Trump arrives on these shores, we and thousands of our supporters will very definitely be making our voices heard.

'In the 15 months of his presidency, we've seen a deeply disturbing human rights roll-back - including the discriminatory travel ban, his reckless announcement on Jerusalem, and harmful policies on refugees, women's rights and climate change.'

British Prime Minister Theresa May and U.S. President Donald Trump famously held hands as they walked along The Colonnade of the West Wing at The White House on January 27, 2017 in Washington, DC.

Mr Trump's visit to Britain, which was first mooted when he took office in January last year, has suffered repeated cancellations and delays.

He was due to come to the UK in February to open the new US embassy in London. But the White House went cold on the idea and cancelled at the last moment.

The Prime Minister was among the first foreign leaders to visit the White House. However, since then, the relationship between the leaders has suffered turbulent moments.

They clashed last year over Mr Trump's tweets sharing anti-Muslim propaganda from a far-Right group called Britain First.

The President also had a run-in with London Mayor Sadiq Khan over the terror threat to the capital.

The new dates for a so-called working visit will be a boost to Mrs May and a sign that relations between Downing Street and the White House have improved.

The two leaders spoke repeatedly and at length earlier this month as they discussed their response to the chemical weapons attacks on Douma in Syria.

British fighter jets joined the US and France in carrying out bombing raids on regime military targets.

There is still no fixed date for an official state visit, which was offered by Mrs May when she visited Washington in January last year.

Mr Trump has developed close ties with Emmanuel Macron of France.

He was invited to be guest of honour at the Bastille Day celebrations last year, when his 24-hour visit was topped off with a military parade.

He and his wife Melania dined with the French President and his wife Brigitte at the Eiffel Tower.

UK diplomats have become concerned about the French stealing a march on relations with the US.

This week Mr Trump hosted President Macron, the first state visit by a foreign leader since he entered the White House.

Ministers have discussed plans for Mr Trump to meet the Queen at Balmoral Castle before visiting one of his two golf courses in Aberdeenshire and Ayrshire.

More than a million people signed a petition last year calling for Mr Trump's state visit - which could have included a stay at Buckingham Place - to be cancelled

Officials believe using the Royal Family's remote estate would prevent embarrassing scenes where he is confronted by thousands of demonstrators.

Mr Trump is said to have expressed an interest in playing a round of golf at the Queen's nine-hole course at the Aberdeenshire castle.

The President had been due to open the new £1billion US embassy at Nine Elms in south London in February.

He said he had dropped the visit because the old embassy in Mayfair had been sold on the cheap.

Jeremy Corbyn has said Mr Trump should not be invited and urged his followers to turn out in force if the US President visited the UK – to send him a 'clear message'.

More than a million people signed a petition last year calling for the state visit to be cancelled.
