FORMER British prime minister Margaret Thatcher is "absolutely fine" in hospital after undergoing a minor operation, a spokeswoman said.
The 87-year-old was admitted to hospital yesterday and is expected to be kept in overnight tonight after having a growth removed from her bladder.
"She is absolutely fine," the spokeswoman said of the ex-premier, who has suffered some ill health in recent years.
Baroness Thatcher was not well enough to join the Queen for a lunch with former and serving prime ministers as part of the Diamond Jubilee this summer.
And two years ago she missed an 85th birthday party thrown for her by Prime Minister David Cameron at 10 Downing Street.
In October she was sufficiently well, however, to mark her 87th birthday with lunch at a restaurant in London's exclusive St James's district with her son Mark and his wife.
The Iron Lady drew criticism from Mr Cameron and others for concentrating on the dementia she has suffered after a series of small strokes. Meryl Streep won an Oscar for the role.
