A hacker has posted sexually explicit comments on the Twitter, Facebook and blog accounts of Tory Member of Parliament Therese Coffey.
According to a report in the East Anglian Daily Times the messages included unpleasant remarks about Prime Minister David Cameron's wife, Samantha Cameron.
In an interview with the newspaper the MP for Suffolk Coastal said: "I came back to my computer and discovered someone had hacked into my website, blog, Facebook and Twitter - it is very frustrating."
She said she was having particular trouble getting help to regain control of her Twitter account.
"I have managed to get control back of them all apart from Twitter - I am still having trouble getting hold of anyone."
