A Tory MP has been questioned over allegations he sexually assaulted a man at a bar in his constituency.

Ben Howlett, MP for Bath, voluntarily attended a police station to speak with detectives after a complaint was made, it was reported.

It is alleged the 30-year-old, who is openly gay, sexually assaulted a man after a Eurovision Song Contest party in May.

Howlett was reported to have been "very drunk" at the time of the alleged offence.

A spokesman for Avon and Somerset Police said the MP had not been arrested and that enquiries were ongoing.

They said: "A man in his thirties voluntarily attended a police station for interview following an allegation of sexual assault."

The night of the alleged incident had reportedly seen Howlett attend a party at a private residence in Bath before guests moved on to a bar in the city centre, The Sun reported.

More drinks were then had by the group at The Common Room pub, where the alleged assault by Howlett was said to have occurred.

Howlett became an MP in 2015 and sits on the Women and Equalities Select Committee. His office did not immediately respond to a request for a comment.

The Conservative Party is understood to be aware of the allegations but said it would be "inappropriate" to comment.
