The matter under discussion is the "deal agreed by European finance ministers in May last year on the European Financial Stabilisation Mechanism (EFSM), making all EU nations liable to contribute to potential euro bailouts". Alistair Darling, then Chancellor of the Exchequer represented this country and on our behalf though without bothering to ask our opinion, agreed to the deal and signed us up to an open-ended bail-out sum. The question is not whether Georgie-Porgie knew about it - nobody is denying that he did as Mr Darling, quite properly, consulted him - but whether he agreed to it. This is what Douglas Carswell MP has been trying to find out, as different people give different versions.
The controversy for Carswell surrounds what Osborne did or didn't agree with Darling.Some say this and some say that and what I say is that Lord Willoughby de Broke is right: one Parliament cannot bind its successor. As this government seems reluctant to act upon that principle, one cannot help feeling just a teensy-weensy bit suspicious.
The Clacton MP has seized on a Treasury document signed by Treasury Minister Justine Greening from July last year (highlighted by Paul Waugh on his blog at the end of last month) which suggests that there was a "cross-party consensus" over the EFSM.
Yet there has been a series of strenuous denials to the Commons that Osborne agreed with the decision made at the meeting in Brussels on May 9th.
