Deputy Labour leader Harriet Harman has been forced to change the password on her Twitter account after it was hacked, she told MPs today.

Ms Harman did not say what was in the “bogus Tweet” on the microblogging website but said: “I wouldn’t ever send a Tweet like that.”

The admission came as Labour former minister Janet Anderson urged the Government to look into an array of “fake” Twitter accounts in the names of all north-west MPs.

And last week Telford MP David Wright launched an investigation into how a comment appeared on his Twitter page branding Conservatives “scum-sucking pigs”.

The Labour MP denied using the words himself and claimed a hacker had got into his Twitter account and changed what he had written.

During Commons exchanges on upcoming parliamentary business, Commons Leader Ms Harman said there was a “real problem here” and promised to “see what Government ministers might be able to do about this”.

She added: “In fact my own Tweet account was hacked into this week . . . and a Tweet was purportedly sent by me widely, which I can assure everyone was not from me.

“And I actually got a response to that bogus Tweet from the former shadow leader of the House who is now the (shadow) prisons minister (Tory Alan Duncan).

“I’ve got to get back to him and tell him it wasn’t from me – I wouldn’t ever send a Tweet like that.”
