It must have seemed like a good idea at the time.

How to attack the Prime Minister’s Brexit strategy?

Why not compare her to Blackadder's Baldrick, infamous for regularly suggesting a "cunning plan", which would often turn out to be but.

That is exactly what Labour leader Jeremy Corbyn did at Prime Minister's Questions (PMQs).

Alas the veteran socialist failed to anticipate that perhaps Baldrick might have passed verdict on Mr Corbyn in the past.

And that is exactly what he had done - well, the actor who played him anyway.

In fact, Tony Robinson had called him "inept" - at media management.

Mrs May thought she was on to a good wheeze, telling the Islington MP: "I'm interested that you chose Baldrick. Of course, the actor playing Baldrick was a member of the Labour Party, as I recall."

It was a claim too far.

Mr Robinson used the social media website twitter to tell her “Haven't left, active member for 40 yrs. But if David Davis needs any help with Brexit Baldrick stands ready to serve."

Earlier Mrs May had claimed that Mr Corbyn was trying to poke fun at her phrase “Brexit means Brexit”.

Wags suggested that it did not take much.

But after weeks of rather too many politicians making jokes of the calibre of “breakfast means breakfast”, it was left to Mr Robinson to win this particular game hands down.

“Baldrick means Baldrick #pmqs,” he tweeted.

Expect to hear that one again.

Later the SNP’s Angus Robertson asked the Prime Minister if she would pressure Spain to refuse to refuel Russian ships headed to take part in operations in Syria.

Mrs May ducked the question, although aides later said that the UK had contacted Spain over the issue.

Perhaps the Tory leader was preoccupied.

She managed to name her party's candidate for West Midlands mayor twice in the fairly short.

The election itself is not until next May.

What odds can I get that he will be namechecked another 98 times before then?
