Just a quickie before the bank chiefs are up.

I hope the MPs have done their homework for today's Treasury Committee.

The bank chiefs are going to know in intricate detail what they're talking about, and there's a danger some MPs might be shown up as grandstanders and nothing more.

I'm told we're going to hear an apology.

In the greater scheme of things it won't make much difference, but in terms of theatre it should be a good watch.

Catch it on Parliament TV, I'll give you a run down later too.
