David Cameron got a reality check last night when the International Monetary Fund trimmed its forecast for Britain and global economic growth this year and next year.
It reckons Britain's economy will expand by only 1 per cent in 2012-13 - 0.1 per cent less than previously predicted.
Its forecast for next year has been downgraded from 2.2 per cent to 1.9 per cent since October.
The IMF's World Economic Outlook update predicted that the global economy would grow 0.1 per cent less than anticipated in each year, by 3.5 per cent and 4.1 per cent respectively.
