Kate Middleton’s photoshop fail on Mother’s Day is not her fault, says an expert.

The Princess of Wales, who tried to edit herself into a picture with Prince George, Louis and Princess Charlotte on a special Mother’s Day wish, did not get the right assistance.

Royal author Tom Bower tells The Sun: “I think the palace played it appallingly at that stage and landed her with that dreadful situation where she did the Photoshop photograph, which was just a tragedy, a self-inflicted wound.”

“They could have avoided all that it had only they’d thought far more carefully about it.”

He added: “I think that there was a period where Kate clearly where people say ‘what's wrong with her’ and the trolls were inventing all sorts of falsehoods.”

This comes as Kate takes a sabbatical from her Royal duties amid cancer treatment.
