On Wednesday Bob Diamond will be hauled before Andrew Tyrie MP and the rest of the Treasury select committee to explain his role in the Libor scandal. Here are a few of the questions he will have to answer.

1. When did you know about the attempts to manipulate the Libor rate at Barclays?

2. What did you do about it when you found out?

3. Have you considered resigning?

4. How many people have you fired over the scandal? Are any of the people who were involved in the interest rate rigging still working at the bank?

5. Are you going to give back the money you have earned since 2006 (the date of the now infamous emails between traders)?

6. Do you stand by your statement to the Commons Treasury select committee in January 2011 that the "period of remorse and apology for banks … needs to be over"?

7. Do you regret the hypocrisy of the BBC Today programme lecture last November when you urged bankers to be "good citizens"?
