David Cameron failed to drive home his main point, that Brown's policies had failed to bring us out of recession, and instead was deflected onto responding to a fatuous point made by Brown about Inheritance Tax. Labour backbenchers loved it. For the first time in his Premiership Brown got genuine, rather than orchestrated, cheers. He even managed to follow up his dusting down of Cameron with a contemptuous remark about Nick Clegg and how grateful Barack Obama would be for Clegg's support.
It was an impressive performance, even though it sticks in my throat to say it. The question is, can he do it week after week? And if he did, would it make any difference to the electorate at large? Probably not, but it makes Labour MPs feel better, and that's an important priority to Brown at the moment.
