Osborne has repeatedly stated that when Darling signed up to the European Financial Stability Mechanism last May, he had spoken to him and disagreed. This memo has now come to light in which it seems to be clear that Darling's actions had "cross-party consensus":
The country had no effective government at the time because Labour had been voted out but the Coalition hadn't yet been formed. However, constitutionally, Ministers remain in place until a new government is formally installed and it was on this basis that Darling went to Brussels and signed on the dotted line.
Cameron has consistently supported Osborne's version of events and did so again this afternoon in the House but this memo throws doubt on their claims. Cameron says our commitment to the EFSM runs out in 2013 and seems to think we should be grateful for that. Let's see, first Ireland, next Portugal, Spain isn't looking too clever, neither is Italy, France also has been mentioned - the list of euro-zone countries in possible financial need is growing and a lot can happen in two years. If Portugal goes then Spain could follow - all well before Britain can begin to dodge the bullets in 2013.
One other point, Darling has said he signed because the EFSM would have gone through anyway on QMV - in that case, why didn't he just abstain? He didn't actually have to sign the EFSM agreement at all.
