The scandal involving traders at Barclays threatened to spill over into the political sphere this week. Bob Diamond released notes of a phone call with the Bank of England and hinted at the involvement of "Whitehall officials" in artificially massaging London's benchmark interest rates known as Libor.
We hear from Guardian City editor Jill Treanor who explains everything you need to know about Libor-fiddling but were too confused to ask.
In the studio to discuss the political implications of it all we have the Observer's economics editor Heather Stewart alongside Guardian columnists Martin Kettle and Seumas Milne.
Among the questions that still need to be cleared up are what key figures in the Brown government knew about attempts to manipulate Libor and whether they were complicit in the terrifying crisis period of the autumn of 2008. It also remains to be seen how parliament will respond and what Vince Cable will make of it all - his attempts to be tougher on the banks have so far been resisted by the Treasury.
Plus - could there finally be some good news to report from the European crisis? Germany may appear to have relaxed some of its bailout condidtions but it's not time to crack open the Bollinger just yet. And, among questions we can't answer: does David Cameron want a referendum on European Union membership or not?
