The "Iron Lady", aged 88 years, died Monday morning, according to her spokesman.
"It is with great sadness that Mark and Carol Thatcher announced that their mother Baroness Thatcher died peacefully following a stroke this morning," Lord Timothy Bell her spokesperson said.
The Iron Lady led the British Government from 1979 to 1990. She is the only Prime Minister re-elected three times on a row in 160 years of British History.
The Iron Lady’s second visit took place in 1975, between August 30 and September 3rd, this time in her capacity of Conservative Party leader, on which occasion she met the leader of the Romanian Communist Party, Nicolae Ceauşescu.
She did not return as prime minister, although in 1980, her Foreign Minister, Lord Carrington, made an official visit to the Romanian state, and in April 1981 Ilie Verdet, as Prime Minister, was received in London by Margaret Thatcher.
