His competence isn't really the issue though. Even his biggest opponents admit that he's principled to a fault. He's spent his whole career rebelling against his own side on points of principle, attending anti-government protests and rallies, etc.

I wouldn't necessarily expect Corbyn to organise an effective opposition to this bill, but I would expect him to offer some opposition. For him not to do so is not just disappointing, it's unbelievably weird. It's the kind of unexplained weirdness that means you have to start asking what is going on, and what kind of pressures are being applied, in order to prevent him doing so.
