Gilian Keegan says the allegations against Conservative MP Crispin Blunt are "serious", but that all the party can do is "act quickly in these cases".
It comes after Mr Blunt was arrested on October 25 on suspicion of rape and posession of controlled substances.
The MP for Reigate has had the whip suspended, but claims his arrest was "unnecessary" and that he is "ready to co-operate fully" with the police investigation.
