The National:

ONCE again, Nicola Sturgeon has taught Theresa May a lesson.

Today’s class was about the art of not making yourself look incompetent.

The UK’s blunderer-in-chief was in Grimsby to entertain a presumably delighted audience of wind turbine workers.

Mustering the kind of subtlety Boris Johnson displays when pretending he doesn’t want to become Prime Minister, May made a bid to scare MPs and the EU into backing her withdrawal proposals.

"Next week MPs in Westminster face a crucial choice: whether to back the Brexit deal or to reject it,” she said looking ahead to another Westminster vote on her withdrawal agreement.

"Back it and the UK will leave the European Union. Reject it and no-one knows what will happen.

"We may not leave the EU for many months, we may leave without the protections that the deal provides. We may never leave at all."

The Prime Minister said that rejecting the deal would mean "the only certainty would be ongoing uncertainty”. Cryptic stuff.

Deciphering this sophisticated code was clearly beyond the Jouker, but Nicola Sturgeon saw right through May’s comments.

Responding to the PM’s claim that “no-one knows what will happen”, Sturgeon provided some much-needed advice to the Tory leader.

“In the olden days, when the UK still had a functioning government, it might have been considered the job of the PM to work that out,” the First Minister tweeted.

For Theresa May, the report once again reads: Must do better.

As ever, Sturgeon wasn't the only one with a bone to pick with the Prime Minister.
