Belated observations on this week's Prime Minister's Questions, which, like the indispensable Paul Waugh, I thought was a significant moment. For the first time, I thought David Cameron looked properly prime ministerial; he held the House.

Gordon Brown's performance was simply lamentable. This was not a matter of the "zero per cent rise" in public spending in 2013/14, which was just a mistake: he meant to say 0.7 per cent. It was a matter of his ruthlessness with the truth. Cameron explained why the Government's plans, including a forecast for the costs of "unemployment, which, sadly, will go up", implied spending cuts in all other departments.
