Conservative MP David Morris said he was "deeply troubled" by former health secretary Andy Burham's comments about the Care Quality Commission.
The MP for Morecambe and Lunesdale, who has written to Mr Burnham, said: "I was deeply troubled to read you had 'no immediate recollection' of any conversations about Morecambe Bay. A feeling that has been strengthened by your admission on today's Murnaghan that conversations may have happened.
"In their evidence to the Mid Staffordshire inquiry, both Baroness Young and Roger Davidson refer to 'pressure' from the last Labour Government while you were health secretary.
"You have denied this in the strongest possible terms, which leads me to conclude that you are implying that they both misled the inquiry, despite being under oath?"
Conservative MP David Morris said his website has been hacked by an organisation claiming to represent "Freedom for the Mujahideen".
Mr Morris, who represents Morecambe & Lunesdale, said: "I was shocked to discover that my website has been hacked. I have alerted the company who host my website as well as Lancashire Police."
He also tweeted: "My website has been hacked, currently working on the situation please e-mail or telephone until further notice."
A spokeswoman for Lancashire Police said: "We received a report from a complainant relating to a website and an investigation is under way."
