Conservative MP Jacob Rees-Mogg, a respected authority on Britain's constitution, has been left baffled - by memes of himself.

The upper-class Tory backbencher was shown a series of pictures that have gone viral on social media and responded with complete confusion.

One photo showed him slumped on the House of Commons benches during a speech by fellow Tory Bill Cash, along with the caption "Paint me like one of your French girls".

Mr Rees-Mogg said: "There I am listening to the great Mr Cash speak and I always think it's important to sit comfortably in the chamber, particularly if you're in there for a long time. I don't really follow the headline..."

On being told it was reference to the film 'Titanic', he replied: "Is it? That's the most boring film I've ever watched".

Another image, of him drinking with Nigel Farage, was captioned with '"Relationship like this please". The confused MP commented: "Er...yes, splendid".

He added: "Nigel Farage was very important in the Brexit campaign and ensuring that we won. He appealed to a crucial segment of the electorate, mainly Labour voters."

Shown a picture of his family below an image of the Kardashians, Mr Rees-Mogg said: "There we are with my fifth child and fourth son all together at my mother-in-law's house in Kent...and there are some people up above who I'm afraid I don't recognise. Do you know who they are?"

Told the people in the other picture are the Kardashian family, he replied: "Oh are they? Who I've heard of but I haven't met...I'm sure they do what they do very well."

The MP appeared lost for words on several occasions, including upon being shown a meme suggesting children wanted to be Jacob Rees-Mogg, rather than fireman, policemen or doctors, when they are older.

He commented: "Erm...erm...yes. Well, I'm sure lots of children want to be firemen, policemen, doctors, and no doubt some want to be politicians as well."

A photo of the MP claiming he had the "ideal male body" that symbolised "peak performance" was dismissed as sounding "rather like a car advert".

The Tory was more forthcoming on an image of his face superimposed onto that of a cat. "Oh splendid, yes, erm, Mogg and cat obviously have a certain similarity. Um, that cat looks a little bit deformed", he said.
