What goes around comes around.
Within the Cabinet of Margaret Thatcher’s Government there grew, over many years, a disgruntlement at her ever increasingly excessively forceful nature.
This came to a head when Sir Geoffrey Howe, one of Thatcher’s closest allies during the entire 1980s, gave a damning speech against her in the House of Commons.
Soon after, a stalking horse, the back bencher Sir Anthony Meyer, challenged Margaret Thatcher to a Leadership contest of the Conservative Party and therefore of her position as Prime Minister of the United Kingdom. Into the short list of candidates Michael Heseltine threw his political hat.
The resulting winner was neither Thatcher nor Heseltine but John Major. He therefore became both the Conservative Party Leader and also the new Prime Minister on November 27, 1990.
In 1992, Stella Rimington was appointed the Head of MI5 (Director General of the Security Service).
