Andy Burnham has described the reports of debauchery at the Presidents Club fundraising dinner as "horrendous" adding that "it's part of that corporate culture that we've got to clear out."
Burnham was speaking to Julia Hartley-Brewer as the scandal surrounding the Presidents Club continues to rage - even though the club itself has opted to close down.
The Financial Times, which sent an undercover reporter to a recent men-only dinner at the Dorchester Hotel, published an article yesterday about hostesses being groped, sexually harassed and propositioned, prompting a national outcry.
Burnham, the Mayor of Greater Manchester, said the scandal must be a harbinger of genuine and lasting reform, adding that he dislikes the idea of men-only events.
"As somebody with two teenage daughters, I think it's time the world changed," he told Julia. Stuff like this has gone on too long.
"No-one should go to work and expect to be groped or abused."
Burnham, who this morning has been out on the streets with rough sleepers in Manchester, also backed John McDonnell's plan to give a lecture to the World Economic Forum on inequality.
"Someone's got to say some home truths," Burnham said. "Society is becoming more and more equal. People at the top are paying themselves too much.
"If John's going there with a strong message of that kind today, good on him.
