In the same interview with Der Spiegel we have from his masters voice:
Corbyn: I think a lot of people have been totally angered by the way in which their communities have been left behind. We had high Leave votes in the most left-behind areas of the country. In a lot of deprived areas, working conditions have deteriorated over the decades, protected by European legislation. Indeed, we would enhance workers' rights, where the Conservative Party wants to go in another direction of a largely deregulated economy.

Stunning doublespeak! High leave votes in the most left behind parts of the country.I wonder what that means? The industrial labour heartlands voted for out, resoundingly. Where and what are these most left behind parts? A meaningless concept unless defined.
He also says:In a lot of deprived areas, working conditions have deteriorated over the decades, protected by European legislation.
Does he realise what he said? or perhaps this is why he supports brexit, so the tories can protect working conditions with positive legislation? Where the conservative party wants to go in fact.
