Don’t bottle it Jeremy

Don’t expect him to call for a second referendum though – he made it quite clear when The New European interviewed him this week that the party still backs the result of June 24, 2016.

But he can sense an opportunity he can surely not ignore – the chance to inflict potentially fatal damage to Theresa May’s premiership.

The whispers around Westminster suggest he could support Britain remaining in the customs union. If he whips his MPs to support the amendment along those lines tabled by Tory rebel Anna Soubry and the government is defeated it would be a direct challenge to May.

And if other amendments also end in defeat for the government May could be forced out. Brexit will claim more political scalps – and in all likelihood May will be one of them.

Some Labour figures have suggested Corbyn’s speech will simply ‘flesh out’ the current thinking. He must go further than this – the young people, those on low wages and those scarred by years of austerity deserve a Labour Party many of them voted for to provide proper opposition to the government on Brexit.

This is Corbyn’s big chance. Will he take it?
