TV presenter Jonathan Ross has said he is "horrified" by allegations of sexual misconduct against David Walliams and the rape conviction of Russell Brand.
In a statement, Ross said he was once "on friendly terms with both men", but that at the time he was "genuinely unaware of their conduct".
ITV News and the Guardian on Tuesday published reports alleging that Walliams has been accused of sexual misconduct by several women. Walliams denies all the allegations against him. Brand was sentenced to 10 years in jail for rape on Monday.
Culture Secretary Lisa Nandy said that the allegations against Walliams were the "latest in a long line of reported abuses of power" in the media.
Ross said he was "as horrified by the revelations about David Walliams and the crimes of Russell Brand as the rest of the nation".
He added: "My thoughts are with the many, many women who have bravely come forward."
Jonathan Ross is one of the country's best-known TV presenters, having regularly hosted celebrities on his Jonathan Ross Show, including David Walliams and Russell Brand.
In the ITV documentary revealing the allegations, Ross is pictured at an event also attended by a woman who later made accusations about the conduct of Walliams.
