Thatcher stepped away from public life in 2002 after a stroke. She suffered several other strokes in the following years.
She made few public appearances in her final months, missing a reception marking her 85th birthday hosted by Prime Minister David Cameron in October 2010. She also skipped the July 2011 unveiling of a statue honoring her old friend Ronald Reagan in London.
In December 2012, she was hospitalized after a procedure to remove a growth in her bladder.
"It is with great sadness that Mark and Carol Thatcher announced that their mother Baroness Thatcher died peacefully following a stroke this morning," said her spokesperson Lord Bell on Monday.
