Scottish Conservative leader Ruth Davidson has posted a picture of herself running through a field of wheat, becoming the latest in a long line of people to openly mock Theresa May's claim that it was the naughtiest thing she had ever done.

The claims by the Prime Minister in an ITV interview with Julie Etchingham have been much derided, but rarely by powerful figures in her own party.

Ms Davidson posted the photo of herself on Twitter and wrote: “I was encouraged to run through their field of wheat. Naughty.”

She made the joke during a visit to Edinburgh's Gorgie City Farm.

It was, to a great extent, Ms Davidson that saved the Prime Minister's political life during June's election, with the Conservatives taking twelve seats in Scotland, raising their total from one to thirteen.

During the election campaign, Ms May was asked by Julie Etchingham what the "naughtiest thing she ever did" was.

She visibly panicked and replied,: "Oh, goodness me.

"Well, I suppose… gosh. Do you know, I’m not quite sure. I can’t think what the naughtiest thing.

"Well, nobody is ever perfectly behaved, are they? I mean, you know, there are times when… I have to confess, when me and my friend, sort of, used to run through the fields of wheat, the farmers weren’t too pleased about that."
