Mrs T and the House of Windsor.
Those who have stepped inside the mum-of-four's home would probably say she is a few diamonds short of the crown jewels.
For she has turned her modest home into a shrine to the House of Windsor.
And Margaret can sit down to tea with the Royal Family - well, their life-size cut-outs anyway.
Every room is packed wall-to-wall with royal memorabilia. The bizarre collection includes a Camilla Parker Bowles SCARECROW, 16 concrete corgis and slippers.
Margaret, 55, who named one of her sons after Prince Andrew, said: "Even as a little girl, I was interested in the Royal Family. Maybe it's because I was an only child.
"The royals are like an extension of your own family, aren't they?"
Film crews from around the world have visited Margaret, who has a Queen of Hearts stained glass window in her Diana Room. It had to be housed in a specially-built extension of her Wimbledon home.
