Jeremy Corbyn was the only person on stage who could be PM next week, so last night was his chance to look statesmanlike. However, Amber Rudd left him squirming by simply asking how numbers would change under his migration policy.

He also had to fend off the minor party leaders as Tim Farron mocked his lukewarm opposition to Brexit. Paul Nuttall even got a jab in, chiding Mr Corbyn for inviting Hamas to the Commons.

In short, they brought him down to their level. “Never wrestle with a pig,” George Bernard Shaw once warned, you get dirty and the pig likes it. He survived, but his credibility was left tarnished.
