BTW I couldn't agree more with Fraser:
Brown’s breathtakingly bad performance on Marr risks overlooking Liam Fox’s brilliant one. As Andrew Porter has said, word perfect.The contrast was overwhelming: tired, bumbling, patently false Brown - he clearly thinks the voters are a bunch of ungrateful idiots for daring to attack his government; and articulate, fresh and convincing Fox....The Tories badly need to hammer home this narrative – what I have called the “reign of error”. It’s happening to Greenspan in America already. Osborne is doing a fine job, but we need all the Shadow Cabinet rubbishing Brown’s record every chance they get, with the effortless and fluency which Fox managed today.
