LONDON – Margaret Thatcher turned 80 Thursday with a rare return to the limelight – a posh party attended by the queen and the former prime minister’s two successors, all celebrating Britain’s “Iron Lady.” Although she has grown frail after a series of small strokes, Thatcher looked healthy as she arrived at the party about 15 minutes late – a delay that an aide said was due to her taking a congratulatory phone call from President George W. Bush. Wearing a navy blue coat and dress, a string of pearls and – as always – a matching handbag, which was her trademark, she smiled and paused for photographs before slowly making her way into the plush Mandarin Oriental Hotel near London’s Hyde Park. Earlier in the day, her assistant Gilly Penrose said Thatcher was feeling good about her milestone birthday. “Her house is looking like a florist’s and she’s very much enjoying it,” Penrose said. “She’s very philosophical about (her age), because she’s very active still.” Heading the high-powered guest list were Queen Elizabeth II and her husband, Prince Philip; Prime Minister Tony Blair; and Sir John Major, Thatcher’s immediate successor at No. 10 Downing St. Thatcher has become more reclusive in recent years and given up most public speaking on her doctors’ advice, but she remains a powerful force 15 years after leaving office as Britain’s first female prime minister.
