The Central Suffolk and North Ipswich MP Dr Dan Poulter has vowed to "vigorously defend himself" following allegations about his behaviour towards female MPs.
Downing Street have confirmed that Mr Poulter has been referred to the Conservatives' new disciplinary committee as a result of an article that appeared in today's Sunday Times.
In a brief statement, a spokesperson said: “Following a conversation with him, the chief whip has referred Daniel Poulter to the party’s new disciplinary committee for further investigation.”
39-year-old Mr Poulter has denied any wrongdoing though and says he will fight the allegations.
"Dr Poulter denies all allegations of misconduct or inappropriate behaviour and will vigorously defend himself against any such claims," a spokesman for Mr Poulter told ITV News Anglia.
"The Sunday Times story is now in the hands of his lawyers."
Mr Poulter has been the MP for Central Suffolk and North Ipswich since 2010 and served as a health minister in David Cameron's government for three years.
