Barry Gardiner: My hon. Friend is right, but perhaps he has missed a further element of that toxic mix. That is not the role of the rating agencies, although they played their part in bundling up sub-prime mortgages. In order to securitise them into revenue streams for companies, they had looked at the historical rate of default in the sub-prime sector in 2000, when only 5% of the market was being sold to sub-prime borrowers, not in 2005, when the figure was 47%. The effect was that many companies had security streams that were not very secure. The piece of the toxic mix that we need to introduce is the way in which hedge funds brought to bear their financial might.

The Temporary Chair (Mr James Gray) rose—

Barry Gardiner: I give way to Mr Gray.

The Temporary Chair: Order. The hon. Gentleman is not giving way to the Chair, but resuming his seat. He is giving an interesting explanation of the causes of the banking crisis. He must relate his point to amendment 9, which we are discussing, rather than dilating more generally on the subject.

Barry Gardiner: Of course I wish to abide by your ruling, Mr Gray. I am referring to earlier comments in the debate, which I am sure you heard, from the right hon. Member for Wokingham, who was not ruled out of order. He gave an interesting explanation of the history of what we are discussing.

The Temporary Chair: Order. I was not in the Chair at that time. It seems to me important that we relate the debate to what we are supposed to be debating, namely amendment 9. I am not aware of what happened previously, but I suggest that the hon. Gentleman relates his comments directly to the amendment.

Barry Gardiner: I am very happy to do so, Mr Gray. We are talking about a bank levy, and amendment 9 refers to "the Government's analysis behind the rate and threshold chosen for the bank levy".
