Lady Thatcher was prime minister between 1979 and 1990 Baroness Thatcher has pulled out of a visit to Downing Street to mark her 85th birthday because she is suffering from flu.
The former prime minister had been due to attend an event hosted by David Cameron with about 150 friends and colleagues on Thursday evening.
Mr Cameron invited her to Number 10 soon after he became prime minister earlier this year.
Baroness Thatcher’s birthday was on Wednesday.
She previously returned to see Mr Cameron’s two Labour predecessors, Tony Blair and Gordon Brown.
