Should the Tories throw Brown a lifeline at PMQs?

Tories should today hope that David Cameron gets panned in Prime Minister’s Questions. Hope that Brown scores a resounding success, and leaves with the applause of all Labour MPs ringing in his ears. The longer he clings to No10, the larger the next Tory majority will be. He is the single greatest weapon Cameron has.  Tories may delight in today’s Populus poll, but now that Brown-bashing has become a national sport do they want anyone else at the Despatch Box at noon on a Wednesday? Now is the time to throw Brown the lifeline he needs. To bomb. To lose Crewe. I have said before that I can’t see a mechanism for him to go. But the way things are going, Labour may not care. If they can’t find a way, they’ll make one.
