Kate was a commoner when she married Prince William in 2011, but the pair were made the Duke and Duchess of Cambridge on marriage. The wedding brought two families together – the Windsors and the Middletons – and now Prince Charles shares three grandchildren with Michael and Carole: Prince George, Princess Charlotte and Prince Louis.

He said: “All it takes is for the monarch to indicate to her Prime Minister that she would be pleased to hear his recommendation that Mr Middleton be elevated to the Lords.”
He added the Prime Minister, “unless deaf, would take this broad hint
