A Tory minister is now facing questions over his attendance at the event last Thursday.
In the House of Commons, furious MPs suggested allegations of groping and indecent exposure should be passed to the Met Police as they claimed the dinner had seen women "bought as bait for rich men".
Sophie Powell-White, head of the account management team at Great Ormond Street Hospital Children's Charity said: "We are thrilled to be launching this exciting new partnership with Wicked, which will combine fundraising activities and special treats for children cared for at Great Ormond Street Hospital". There is no suggestion he was involved in wrongdoing.
"All monies raised in our name go to support vital work".
The hospital says that it was never supposed to receive money from the dinner but that it will return previous donations and "no longer accept gifts from the Presidents Club Charitable Trust".
One of the charity dinner's chief beneficiaries, Great Ormond Street Hospital, has also announced that it will return all of the money raised for it at the event.
And advertising giant WPP, which sponsored a table at this year's event, announced it will end its association with the Presidents Club.
An investigation by the Financial Times revealed hostesses at the annual event, which is accompanied by an auction, are forced to dress in skimpy outfits, plied with alcohol and groped by guests, which included City grandees.
The Jan. 18 event featured auction prizes of tea with Bank of England Gov. Mark Carney and lunch with Foreign Secretary Boris Johnson. Well, there were still some women: the 130 hostesses hired for the occasion, who had been ordered to come with "tight black clothes, matching underwear and high heels", according to the Financial Times.More news: Los Angeles Clippers vs. Boston Celtics

As burlesque dancers performed on a stage, a 19-year-old hostess was asked by a "guest nearing his seventies" whether "she was a prostitute", which she was not, according to the report, which the FT made available for free viewing behind its traditional paywall.
Labour MP Jess Phillips branded the event a "lady zoo" and has called for "every penny" raised to be donated to children and adult sexual violence services. Meller runs the luxury good specialist Meller Group, and also sits on the board of the Department for Education and the Mayor's Fund for London, Ritchie is a property developer who founded Residential Land, and Soning is also a property developer.
The politician branded reports of behaviour at the event "shocking" and vowed never to attend a men-only function again.
"It is quite extraordinary to me that in the 21st century allegations of this kind are still emerging", said Anne Milton, junior education minister, during the debate.
A spokesperson told Sky News: "We are assessing these allegations as a matter of urgency and will be contacting the Presidents Club Charitable Trust".
The event was hosted by comedian David Walliams.
One argued that just the presence of hostesses at an all-male event didn't make it bad and when informed of the report's details, said maybe the guests had no idea the event would turn out as it did.
A spokesman for the club told Business Insider: "The trustees have decided that the Presidents Club will not host any further fundraising events. Others remained seated and yet insisted on holding the hands of their hostesses. a prelude to pulling the women into their laps", wrote undercover journalist Madison Marriage, who posed as a hostess at the event along with a woman working with her. "Women have the right to feel safe wherever they work and allegations of this type of behavior are completely unacceptable".
"The allegations will be investigated fully and promptly and appropriate action is taken".
