One thing that does impress me about Theresa May. Her ability to keep a straight face.

“People across the country,” she sternly informed MPs today, “are saying, ‘Let’s get on with it.’”

Seriously. That’s what she told them. “Let’s get on with it.” Minutes – literally minutes – after announcing to the Commons that she was postponing the crucial vote on her Brexit deal. And after refusing to confirm when the vote would now go ahead.

Imagine you or I attempted to lecture others about the importance of “getting on with it”, while at the exact same time preventing them from doing so. We couldn’t do it, could we? We’d turn bright red, and break off mid-sentence to apologise. “Sorry, that sounded ridiculous, coming from me, didn’t it?” we’d murmur, with a nervous giggle. “Forget I spoke.”

But not Mrs May. She didn’t look remotely embarrassed. She just sailed straight on, seemingly oblivious to the dazzling absurdity, the awe-inspiring audacity, of what she’d just said.

I wonder how she does it. Practice, I suppose. Two and a half years of practice.
