The MP for Bury St Edmunds, David Ruffley, faces a grilling by his local conservative association after he was cautioned for a reported assault on his former girlfriend.
Mr Ruffley has been the town's MP since 1997. He was given the police caution after officers were called to an address in London in March.
So far the former shadow police minister has not commented publicly on the incident.
His local conservative association are due to hold a meeting with him next week to discuss the issue.
