Ignore the blustering brinkmanship: there will be a deal between Britain and the EU. This week, next week or in the final second before the clock strikes 12, this Brexit-crazed government will sign on the line.
It needs no crystal ball to foresee a deal. Though this government is disgraceful and dishonest, it is not certifiably insane. It will not kill off the car industry, manufacturing, farming, finance and fishing. It will not cut off security and police relations with Europe. Nor will it want a hard border in Ireland, breaking the Good Friday agreement. And nor will it freeze friendship with the new US president, nor leave relations with our nearest neighbours and traders irreparably rancorous.
Agreeing to go to WTO terms is a deal so clearly, yes, there will be a deal. For the default is a deal.
Polly doesn;t mean that of course – and we’re about to find out whether she’s right too.
