There was some quite heavy briefing this morning that Labour Eurosceptics and Labour MPs with leave-leaning seats could be the ones to deliver the government victory tonight, by rebelling against their party and voting against the amendment.

Labour whips say they are pleased tonight that only four Labour MPs did so, all of them long-standing Brexiters. I’m told Denis Skinner, a fervent Eurosceptic but a long-standing friend and ally of Jeremy Corbyn, helped carry many waverers over the line.

But Labour are clearly frustrated that a win was possible but Grieve’s concession meant it was denied.

“Tory MPs had a chance to deliver a truly meaningful vote,” a source said. “Labour MPs remained united - including some being taken through the voting lobbies in wheelchairs - but the so-called Tory rebels lost the courage of their convictions and gave licence for a no deal Brexit.”
