Corbyn still has much left to prove after trip to Yorkshire

But watching him in action in Morley Tuesday night it is easy to see why he might occasionally imagine himself walking into Downing Street next month.

Corbyn to set out education plans in Leeds as both leaders target Yorkshire

After all, how many politicians can attract a crowd to a piece of land outside a leisure centre with barely a few hours’ notice and be greeted by them as a hero even though they are running horribly late and kept them waiting in the rapidly disappearing sunshine?

“Superb” and “get that man in Number 10” were among the cries as Mr Corbyn finished his no-notes speech. And if I heard them, there’s a good chance he heard them too.

Mr Corbyn himself suggested that he gauges the success Labour is having by the size of the crowds he sees as he told the gathering in Morley about the huge numbers who had attended the party’s General Election campaign launch in Manchester earlier that day.

Of course, Mr Corbyn’s ability to rouse a section of Labour’s base support has been clear since his unexpected Labour leadership victory in 2015.

What he has yet to prove is that he can present himself and his policies in a fashion that appeals to centre-ground voters.

And in that regard, events earlier in the day, most notably a BBC interview where he seemed unable or unwilling to clarify Labour’s position on Brexit, continue to seem far more representative of the chances of Mr Corbyn becoming our next Prime Minister.

Mr Corbyn might claim he is meeting more real people than Mrs May on this campaign but that hardly matters if they are already going to vote for him.
