Corbyn might have made an astute political move yesterday. He got the crowd behind him. He even got George Osborne behind him. But let’s be clear what he did not do.
He did not tackle the issue of migration. That was a mistake.
He did not tackle the issue of Ireland: a customs union is a necessary but not a sufficient condition to solve that. Only the single market prevents economic and greater mayhem there.
And it may be that he is backing a parliamentary amendment to supposedly achieve his goal that is not legally binding, so why take the risk?
In that case was yesterday just a manouevre? In reality, did it have substance? It may have looked astute but was it enough? I am not convinced as yet.
What we can say for sure is that Corbyn did not lay out a viable plan for Brexit yesterday. In that sense the shambles at the heart of British politics continues unabated. I welcome a step in the right direction. But things have to go a lot further as yet.
