On the programme, former Conservative Prime Minister, Sir Edward Heath, said the Tories will never return to power with their current policy on Europe. The MP, who will stand down at the forthcoming general election, told the programme it was "not practical politics" to appear to want to withdraw from Europe. Sir Edward - who last month suggested the Conservative Party was on the "extreme Right" - said it needed to appeal to the middle ground to be elected.

Former Labour Deputy Leader, Roy Hattersley, told the programme he did not want to see another huge majority for Tony Blair in this year's general election. He told Sir David that he wants to see a much more radical government, in his words, a 'real Labour government'. He says the ultimate result for the country and for the party would be best if there was a Parliament that could bring more pressure on Tony Blair.

Also on the programme, Conservative Party Chairman Michael Ancram told the programme that the Conservatives continued to be a "broad church". He promised a "very radical" manifesto which "returned power to the people" by allowing them to make more decisions themselves. Talking to Sir David, he accused Labour of making the same pledges as in 1997 because of its failure to deliver.

Northern Ireland First Minister, David Trimble, said the full implementation of the Good Friday Agreement was being undermined and believed republicans wanted it to collapse. Mr Trimble again warned republicans they had to honour their commitment to fully implement the Agreement by June, including putting IRA weapons beyond use.

Also on the programme was one of the highest paid sportsmen in Britain - basketball player John Ameachi, from Stockport. The Orlando Magics player told Sir David about his career, his role as ambassador for the Reading is Fundamental programme, and spoke of his views against gun control.
