Baroness Thatcher remained in hospital today as she recovered from minor surgery.
The 87-year-old former prime minister is expected to spend Christmas in hospital, after being operated on three days ago to remove a growth from her bladder after suffering pain earlier in the week.
Following the operation, she was said to be "in good spirits", and a spokeswoman this afternoon said there had been no change in her condition.
She is not expected to be released from hospital for a few days.
The veteran ex-premier's public appearances have been very restricted over recent years due to continued ill health.
She was unable to join the Queen for a Diamond Jubilee lunch with former and serving prime ministers this summer and missed an 85th birthday party thrown for her 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.
Her health was thrust into the global spotlight this year when Meryl Streep starred in a controversial Hollywood film, The Iron Lady, about her.
The film drew criticism from Prime Minister David Cameron and others for concentrating on the dementia she has suffered after a series of small strokes.Reuse content
