Ed Balls: 'Not at all nervous' about MPs' hearing

Bob Diamond is due to be questioned by MPs, one day after resigning as Barclays chief executive in the wake of the inter-bank interest rate-fixing scandal.

The Commons Treasury Committee will want to know if the Bank of England's deputy governor Paul Tucker knew the rates were being manipulated, and if there was any pressure from the last Labour government to keep them low.

Shadow chancellor and former Treasury Minister Ed Balls has said he is ''not at all nervous'' about what Bob Diamond will have to say.
