Margaret Thatcher has been admitted to hospital after failing to recover from a nasty bout of influenza.
The 'Iron Lady' was forced to pull out of her 85th birthday party at her former residence, 10 Downing Street in London, last Wednesday (13Oct10) because she was too ill to attend.
She urged Britain's current leader David Cameron not to cancel the party, and told the 150 guests in a message that she was "so disappointed" that she wasn't able to make it to the festivities.
The Baroness was taken to Cromwell Hospital in the British capital on Tuesday (18Oct10) as a "precautionary measure".
Concerns for Thatcher's health have escalated following a number of strokes. She broke her arm in a fall at her home last year (09).
