North West Bristol MP Charlotte Leslie is to stand for election to chair the Health Select Committee.
Her announcement comes after current Chair Stephen Dorrell announced he was standing down.
Charlotte Leslie MP is already a member of the committee. She says she wants to "help return our NHS to the service not of politicians and of managers, but to patients and the nurture and support of those dedicated solely to looking after them."
But added her colleagues were "spoiled for choice" in the other candidates.
A Bristol MP could face an investigation over her failure to declare cash donations to her local party.
Charlotte Leslie the Conservative member for Bristol North West apologised to the House of Commons earlier this month for failing to comply with the rules. But now a letter of complaint has been made to the Westminster Standards Watchdog.
Ms Leslie asked questions about the proposed Severn barrage but failed to mention that her local party had received £17,000 from the boss of the Bristol Port Company, which opposes it.
