We reached a tipping point today.

The Government’s chaos on Brexit has become so acute that even Jeremy Corbyn could not resist raising it at Prime Minister’s questions.

Given his party’s own contortions on the issue, the Labour leader has tended to tip toe around the subject.

But now the Government’s handling of the negotiations has become so shambolic he reasoned a few jibes from the opposition was worth the price of taking the fight to the Tory frontbench.

Independent observers would accept this was not Mr Corbyn’s finest outing.

His first question worked well as a scene setter when he raised Liam Fox’s ridiculous claim the negotiations would be the easiest in history.

It was difficult to work out if there was actually a question contained in his next salvo.

They laughed at Theresa May, not with her

And it took until his fourth question for him to raise David Davis’s embarrassing appearance before the DeXeu select committee this morning.

In the end, Mr Corbyn’s failure to land a direct blow did not matter.

The Prime Minister was perfectly capable of damaging herself without the aid of the opposition.

Her replies were delivered with a mock authority that only underlined the ridiculous nature of the words she spouted.

“Very good progress has been made,” on the negotiations, Mrs May told disbelieving MPs.

Unless someone was still drunk from the Christmas party or living in an igloo on the North Pole where no media is available, it would be difficult to find anyone after the last few days who agreed the negotiations were advancing smoothly.

Jeremy Corbyn made the rare decision to press on Brexit

As Mr Corbyn sort of pointed out, the Prime Minister had failed to seal the deal on Monday , cancelled a statement to the Commons and was struggling to find Arlene Foster’s phone number.

Mrs May was not giving up in her fight with reality.

She insisted there were just a “couple of things” that needed to be overcome before the Brexit talks could move to the next phase.

The Labour leader did not need to press the prosecution any further.

He should have sat down as the House erupted in laughter and said “no further questions your honour.”
