Hmmm, I'm not sure I agree. I think Corbyn is playing political games because he himself is anti EU and pro-Brexit but he knows his party is largely Remain. He is also hoping he can force a General Election which he may win.
His refusal to discuss anything with the PM, on the grounds that she wouldn't rule out No Deal is bollocks. The default, if we get to March 29th without an agreement is No Deal. To avoid that, we need to have a parliamentary agreement for something else - a deal of some description. Or an agreement to request an extension to Article 50, or legislation for another people's vote, or the opening of talks on alternative options with the EU. Whatever it is, there needs to be parliamentary agreement and as leader of the opposition, he has some responsibility in that.
I'm not sure that Corbyn has the political interests of the UK at this precise moment at the forefront of his mind. I think he is manoeuvring and not being up front about it.
I'm fairly apolitical, as I find myself not liking any of the current party options available to us very much. I think Corbyn is just as slippery an eel as any other politician and I'm not sure that any of the generous minded attributes applied by Alfie Brown in his article are true!
