Last week, Baroness Thatcher – who was prime minister from 1979 to 1990 – pulled out of a visit to Downing Street to mark her birthday, because of flu.
The BBC understands that she has not completely recovered and the hospital admission is linked to last week’s illness.
In 2005, Baroness Thatcher was advised by doctors that she should not make public speeches in the wake of some minor strokes.
But she still attends some public functions, including a recent address by the Pope during his state visit to the UK.
In March 2008, she was taken ill during a dinner in Westminster and spent the night in hospital as a precaution, bit was later given a clean bill of health.
