SHE prefers to be known simply as Katharine and is fiercely proud of her Yorkshire roots. When she travels she does so without any royal paraphernalia, unaccompanied by bodyguards, and is happy taking a bus or hailing a black cab. She has confided a liking for EastEnders and listening to Michael Bublé and for years she taught music incognito at a primary school in Hull where pupils referred to her as “Mrs Kent” or just “Miss” and had no idea she was married to the Queen’s cousin.
