Under Jeremy Corbyn’s leadership, the British Labour Party – equivalent of the U.S. Democratic Party – has moved back to the far-left vision that defined its policies in the 1970s. Rejecting the neo-liberal leadership of its most electorally successful former leader, Tony Blair, Corbyn’s Labour Party now supports higher taxes, much higher spending, and a vast nationalization program.

Personally, I believe this vision is utterly idiotic. But that’s just me. What’s more interesting is what happened this week, when we got an insight into the internal Labour Party tensions over Corbyn’s agenda. It came via a debate hosted by Novara Media (a pro-Corbyn media outlet). The debate featured Blair’s former top staffer, John McTernan, and Grace Blakeley, an economics analyst for Novara. To McTernan and Blakeley’s credit, they were respectful and debated in good humor.
