Osborne responds to Darling statement

Shadow chancellor George Osborne has called on the chancellor to reveal the total extent of the taxpayer exposure to beleaguered banks, telling MPs that "the British taxpayer is insuring the car after it has crashed".

Mr Osborne was responding to an announcement from Chancellor Alistair Darling that the government will provide another �13bn in funds to RBS in return for shares, and could end up owning up to 84% of the bank.
