Dumb question from the BBC Pest

I quote from the BBC Business Splutterer:

Gilt sales this year are forecast to be £220bn - way above all market forecasts.

There will be a big gulp from investors.

Why is the Treasury's borrowing need so much greater than was expected?

Answer: BECAUSE AS THE IMF SHOWS AND TODAY'S BUDGET PROVES TREASURY FIGURES CANNOT BE BELIEVED - NOBODY KNOWS WHAT THE BANK BAIL OUT WILL COST!!!!(But 60 billion wont come close). Peston should have stayed tuned to the BBC Parliament Channel to hear the whole of John Redwood's first rate speech, linked here, titled "The Damian Mcbride Memorial Budget"
