Nigel Evans, the former deputy speaker of the House of Commons, has denied in court allegations of sexual offences against seven men.
Evans, the MP for Ribble Valley in Lancashire, entered formal not guilty pleas to all charges during a pre-trial hearing at Preston Crown Court.
The 56-year-old stood in the dock, hands clasped at his front, to repeat "not guilty" as each charge was put to him.
An extra count of sexual assault was added to the indictment, making nine charges in all.
He denies two counts of indecent assault, six of sexual assault and one of rape. The charges date from 2002 to April 1, last year.
Evans resigned as Commons deputy speaker after he was charged on September 10.
