Guido hears whispers that any extra cash to the IMF is unlikely to be pledged before April, which means he could well be running around Smith Square naked on St Paddy’s Day as promised. A man of his word…

That hasn’t stopped the Tory whips preparing the troops for the potential vote though. Yesterday the chairman of the Treasury Select Committee Andrew Tyrie wrote in the Wall Street Journal:

“Some have been arguing that the U.K. should stand aside from any increase in IMF resources and let the euro zone stew in its own juice. That would be a mistake—the cost to the U.K. would be high. Instead, Britain should respond to the IMF’s own conclusion that it has financing needs of an additional $500 billion in coming years by agreeing to our share of a global loan.”

He lays out the argument for more borrowed bail-outs and Tory whips are circulating the piece, clearly trying to soften the ground. With a large chunk of the Tory backbenches loathed to contribute more money, coupled with the prospect of Labour opposing it too, it’s going to take more than the odd article and email to win this one.
