George Galloway has been signed up to host a weekly current affairs phone-in show on Talksport radio.
Mr Galloway is promising to be controversial
The Respect MP, who was criticised for taking part in Channel 4's Celebrity Big Brother, will discuss political and non-political subjects.
Mr Galloway said: "I intend to make this the most talked-about talk show on radio - I think I have a pretty good track record of stimulating debate."
The MP was expelled from Labour in 2003 but won an east London seat last year.
Mr Galloway, who represents Bethnal Green and Bow, was ridiculed for pretending to be a cat and performing a robot dance in a leotard on Celebrity Big Brother.
He said: "Most politicians - and most politics - are boring. I don't think even my worst enemy could call me that."
Programme director Bill Ridley said: "We are delighted to have George on our team.
"He's a natural broadcaster. We like our presenters to have strong opinions and they don't come much stronger than George Galloway.
"I can't wait for him to start. To coin a phrase, it promises to be the Mother of All One Man Shows."
The show will be broadcast from 2000GMT on Saturdays and Sundays from March 11.
