This is the almost exactly the same panel that was asked in December whether it believed the Government was right to agree the interim deal that the Government struck with the EU. (Or, to use its proper title, the joint report.) Seven out of ten of the panel’s members supported Theresa May and her Ministers.

This result approaches a complete turnaround. It has come to something when nearly two in three party members have no confidence in their own Party leader’s handling of the Brexit negotiation.

Of course, it may be that their view shifts once again in the wake of the June summit, at which the Prime Minister and her team somehow pull an entire Watership Down’s-worth of rabbits from their collective hat. But it very difficult to see where a triumph will come from given the paralysis on the Government’s customs plans, and much else.
