Campbell interviews Mandelson

The inner workings of Tony Blair's Downing Street are set to be revealed in a TV interview when Alastair Campbell interviews Peter Mandelson.

The frank exchanges between Mr Campbell, the Prime Minister's former director of communications, and his fellow architect of New Labour were recorded for Channel Five this week.

The Alastair Campbell Interviews series begins tonight, and the Mandelson interview will be seen in the next few weeks. Relations between the two men soured after Mr Blair forced Mr Mandelson out of his last Cabinet job as Northern Ireland Secretary partly on the advice of Mr Campbell.

The Channel Five chat show is the latest move into the media spotlight by Mr Campbell following his decision to quit the Government-last year in the middle of the Hutton Inquiry.

Tonight Mr Campbell interviews Lance Armstrong, the US cyclist who overcame cancer to win the Tour de France five times.

Mr Armstrong repeatedly refers to his "obsessive" nature and his all-consuming desire to win - the very character traits that Mr Campbell's friends and enemies alike recognise in the man once dubbed the Sultan of Spin.
