Amendment of the law

I am listening to the right hon. Gentleman's speech with great interest. He mentioned Glass-Steagall. Will he reflect on the impact of the collapse of Lehman Brothers, which was not a deposit taker on the Glass-Steagall model? It would not necessarily have been protected, yet its failure has had catastrophic implications around the world. I wonder whether the distinction is perhaps harder to make today than it was in 1933.
