The difference between you and me is that I'm not partisan or looking at this through the prism of political affiliation. For starters I've not blamed anything on Corbyn, I pointed out that all these events solidify Boris' support within the leave camp while Corbyn has been outflanked by the Lib Dems an is stuck on his fence.
Brexit party will yield to Boris and if you think labour can renegotiate you are clearly ignoring what the EU have said. They gave us a deal, take it or leave it and with the anti-EU factions in Europe milking this for all it's worth I'm not entirely sure an extension is on the cards.
Labour blew it's chance to make a clear brexit position and present it to the people and they will pay for that.
