Further footage has emerged of the undercover sting which exposed sexual impropriety at a lavish charity event where hostesses were groped and harassed.

Revelations that women were grabbed and propositioned at a men-only Presidents Club event attended by politicians and captains of industry have provoked fury.

The club announced it was closing yesterday after 33 years of holding fundraisers for some of Britain's most influential businessmen.

Footage shows undercover Financial Times reporter Madison Marriage using a secret recording device after she heard about behaviour at the event from a friend who previously worked there.

The revelations have led to the charity being shut down and for calls for a government minister to be sacked. It not suggested those in this image took part in any impropriety

Hostesses at the event were told to wear skimpy black dresses, black underwear and 'sexy' black shoes. Some have since said the dresses were much shorter than they had been told about in interviews.

The video Ms Marriage recorded shows her entering the hall where the auction is held as hostesses pour drinks and chat to suited guests.

Above the hubbub, an auctioneer can be heard selling off a package for plastic surgery at a Harley Street clinic.

He says: 'Ladies and gentleman, this is what your missus could look like. Who'll give me ten thousand pounds?'

Ms Marriage later returned to another hotel and told how, although the evening started with decorum, it very quickly 'turned for the worse'.

She said: 'Some of the behaviour was pretty shocking and depressing if I'm honest.'

Madison Marriage, the reporter who went undercover, said she was groped 'several times'

She later told BBC Newsnight: 'I was groped several times and I know that there are numerous other hostesses who said the same thing had happened to them.

'It's hands up skirts, hands on bums but also hands on hips, hands on stomachs, arms going round your waist unexpectedly.'

She added: 'I can't believe that it still goes on in 2018, I think it's quite shocking.'

One hostess, aged in her 20s, who waitressed at the event told ITV News: 'We were play things. We were objects for them to gawp at, touch.'

Another, who asked not to be named, told Good Morning Britain today: 'I experienced a rather bizarre event, not a normal hostessing event that I'm used to.

'Initially it started quite normally and then as the night went on I started to notice that this isn't normal.

'There was a lot of groping, a lot of girls sitting on laps, men beckoning girls over to their table and talking to them. It just didn't seem right.'

The Presidents Club hired 130 women as hostesses at the annual black-tie fundraiser, which was held at The Dorchester hotel in Mayfair last Thursday (pictured in 2012)

The lavish menu for the raucous evening included steak, caviar, salmon and Champagne

She added: 'I felt harassed. I removed myself from the situation and found a group of girls in a similar situation, feeling the same as me, weirded out. I stuck with them so I didn't have to engage so much with the men. But some girls were engaging and flirting.

'The thing for me was towards the after-party when everyone was a lot more drunk and girls were drunk. I think men were perhaps taking advantage of that. I saw a lot of hands up skirts. I saw a lot of grabbing.'

The Presidents Club, which said it was 'appalled' by the allegations surrounding the event last week, has announced it will distribute remaining funds to children's charities before shutting down in the wake of the scandal.

Theresa May is set to target gagging orders that prevent women reporting sexual harassment, according to The Times.

Such a move would come in the wake of reports that hostesses at the event had to sign confidentiality agreements.

Revelations arising from the event prompted the resignation of businessman and Presidents Club trustee David Meller.

He quit his role at the Mayor's Fund for London and the Department for Education.

In a statement the Dorchester said it had a zero-tolerance policy regarding harassment of guests or employees
