Showing the kids where granny used to work, Margaret Thatcher slipped into the spectators' gallery at the House of Commons with her son's children.

Lady Thatcher, Conservative Party prime minister from 1979-90, drew scarcely a second glance.Dressed in a blue suit, one of her hallmarks in power, she pointed out where she used to sit at the head of ranks of Tory legislators. Thatcher, 74, leaned close to Michael, 11, and Amanda Margaret, 7, apparently explaining what was going on.

The children and their father, Mark Thatcher, are visiting from Cape Town, South Africa, where Mark and his wife, Diane, moved to several years ago.
