Every day brings a new low for Jeremy Corbyn but still the man clings to power like a limpet to a rock. This Wednesday’s Prime Minister’s Question Time saw outgoing David Cameron adding his name to the growing list of MPs demanding the Labour Leader’s resignation. “For Heaven’s Sake man – Go!” Cameron barked across the dispatch box to woops and cheers from the House.

It is remarkable that despite having lost a key referendum on Britain’s future in the last week, it was still David Cameron who was the one on the offensive. But such is the level of crisis in the Labour Party right now that the Tories seem quite dignified in comparison. A vote of no confidence on Tuesday showed that Corbyn could only muster 40 Labour MPs to support him with an incredible 172 voting against him. Corbyn’s Shadow Cabinet is depleted with few people outside Westminster able to name a single one of his Shadow Cabinet. From comical to farcical, Pat Glass, Corbyn’s latest choice for the Shadow education brief could only stomach a front bench job for three days, announcing her intention to stand down as an MP the day after being appointed and quitting Corbyn’s line up the day after. But still, Corbyn battles on and with every day that passes without his resignation, one can’t help that come to the conclusion that he will continue to dig his heals in and fight for his position to the death.

Corbyn is a deeply principled man. Even his most fierce detractors have had trouble denying that. The problem is that trying to persuade a man like Corbyn to think pragmatically is utterly alien to him – it’s just not going to happen. Surrounded by hard left ultras they want their man to hold fast come what may. Corbyn believes that he has a democratic right to be Labour leader and he looks unlikely to deviate from that principled stance, regardless of how practically impossible it has become. There is likely to be a leadership contest to try and bring Corbyn down, with Angela Eagle looking set to throw herself into the ring as his primary competition. However, it is quite possible that Corbyn could win another leadership contest and after what would be months of infighting and destruction, Labour would end up exactly where it started. Whether there is a Labour Party of any description left at the end of this is quite another question but one that Team Corbyn seem utterly oblivious to. Dark days indeed for Labour.
