Denis Thatcher died the following year; they had been married more than half a century.
Thatcher’s later years were marred by her son Mark Thatcher’s murky involvement in bankrolling a 2004 coup in Equatorial Guinea. He was fined and received a suspended sentence for his role in the tawdry affair.
She suffered from dementia in her final years, and her public appearances became increasingly rare. British media reported that Thatcher had been staying at the Ritz because her Belgravia home did not have an elevator and she was having difficulty getting around.
She is survived by her two children, Mark Thatcher and Carol Thatcher, and her two grandchildren.
