Baroness Thatcher is apparently recovering well in hospital. I pray for her speedy recovery. God Bless the Iron Lady
The 85-year-old former prime minister was taken to Cromwell Hospital in Kensington for “routine” tests and treatment.
A spokesman said her condition was not serious but was better treated in hospital than at home. Her son, Mark, said the admission was "a precautionary measure". She is expected to leave hospital within days.
Lady Thatcher had to pull out of a party held at Number 10 Downing Street for her birthday last last week after falling ill with suspected flu.
The 85-year-old sent a message to David Cameron, who hosted 150 guests in her honour last Thursday, saying: “On this particular occasion I have had to accept that the Lady is not for returning. Please, please enjoy yourselves.”
She is understood not to have fully recovered from last week's illness. Aides called in a doctor to assess her condition this afternoon and she was taken from her home to hospital shortly afterwards.
Mr Cameron said her wished her a "speedy recovery".
