You can see where they're all coming from. As I wrote yesterday, there's much that was impressive in Osborne's speech. But there were also some weaknesses on the policy side of things. Allister Heath puts it best in City AM:
"Yesterday’s proposals to trim spending are to be welcomed but amount to at best £7bn a year; yet the budget deficit this year could hit £200bn. Freezing public sector wages for those earning over £18,000 is a brave decision given the election is less than a year away; but it will save just £3.2bn in 2011. It goes no more than 1-2 per cent of the way towards eliminating the structural part of the deficit."
Osborne will need to do much more if the Tories are to win a mandate sufficient to the task awaiting them - and all of the politicos I've spoken to in Manchester recognise that. You can expect the Tories to set out more "fine print" around the time of the Pre-Budget Report.
