"Close allies insist that Brown will focus on the domestic agenda once the G20 show is over, and that he knows the Budget on 22 April will be much more important to his chances of staging another political fightback. 'He has not staked all his chips on a one-day summit,' one said. 'He will move on quickly. He has still got a lot of chips left.'"
Still got a lot of chips left, has he? Brown and his allies would do well to remember that - as I pointed out a few weeks ago, and as Anthony Wells kindly backed up with a more detailed analysis - recent Budgets haven't tended to deliver a boost for the government. After Mervyn King's comments the other day, and given the dire state of the public finances, it's hard to imagine Brown bucking that trend this time around.
