Politics Weekly podcast: Tony Blair jets in to savage David Cameron

The Trimdon Labour Club played host to a return to campaigning for Tony Blair . His speech tore into the alleged contradictions in David Cameron's policies and heaped praise on his successor Gordon Brown. But how will it go down with the public? And will Labour MPs want the former prime minister out on the campaign trail with them? Also in this week's show: George Osborne has pledged to axe Labour's national insurance hike. A masterstroke or an irresponsible giveaway? And, after a polite debate between the would-be chancellors, we ask if the leaders' debates will be as crucial as conventional wisdom will have you believe. Spectator editor Fraser Nelson has his doubts. And did you spot the Guardian's April fool ? One of our guests didn't. Leave your thoughts on any of this below.
