South African political parties paid tribute to former British Prime Minister Margaret Thatcher.
The 87-year-old baroness passed away following a stroke on Monday morning, her spokesperson said.
The Freedom Front Plus remembered her as a staunch anti-communist.
"[We] express our sympathy with the British nation with the passing away of Baroness Margaret Thatcher," FFPlus international relations spokesperson Corne Mulder said in a statement.
"Baroness Thatcher was the only female prime minister to date in British history.... She will be remembered for her strong views against communism and socialism."
Mulder said she and former United States president Ronald Reagan, who died in 2004, played a huge role in the final destruction of communism.
"In so doing, she did the world a big favour. She was widely respected and made a big impact on British and world politics," he said.
Inkatha Freedom Party (IFP) leader Mangosuthu Buthelezi also paid tribute to her, noting her as a voice of reason.
"She was a voice of reason during apartheid and listened attentively to my plea against sanctions and economic disinvestment, which we both recognised would hurt the poorest of our people the most.
"I was privileged to visit Lady Thatcher at 10 Downing Street in 1986, and was honoured when she specifically travelled to Ulundi to visit me as the Chief Minister of the erstwhile KwaZulu Government," Buthulezi's statement continued.
"Never before had an international dignitary shown such respect for a black leadership. She displayed all the best features of a trailblazer; the courage of her convictions and a tenacious belief in doing what was necessary and right."
Former president FW de Klerk said Thatcher had a better grasp of the complexities and geo-strategic realities of South Africa than many of her contemporaries.
A steadfast critic of apartheid, she had consistently and correctly believed that much more could be achieved through constructive engagement with the South African government than through draconian sanctions and isolation, De Klerk said in a statement.
She had understood the need to consider the concerns and aspirations of all South Africans in their search for constitutional consensus.
"For this reason, she was able to play a positive role in supporting our own process of non-racial constitutional transformation in South Africa," he said.
"We met in the Cape and in London many times after her retirement from office, and before her stroke in 2002. I am honoured to have had Margaret Thatcher as a friend," he said.
