Margaret Thatcher was Britain’s first female prime minister who held the office from 1979 to 1990. She was also a leader of the British ‘Conservative Party.’ She won three consecutive terms of office in two decades and became the only British prime minister in the twentieth century to do so. One of the most influential prime ministers of Britain, Thatcher was also the most debated stateswoman of the century, earning both respect and hatred from the public, particularly for her treatment of trade unions. She transformed the ‘Conservative Party’ into one of the most successful political parties in Britain. She earned the nickname ‘Iron Lady’ because of her leadership style and radical ideologies, which came to be known as ‘Thatcherism.’ Her journey from being a humble grocer’s daughter to winning the position of secretary of state for education and science is an inspiring one. Following her appointment as the prime minister, she introduced a new wave of economic initiatives. Margaret Thatcher was a woman of staunch values who brought about radical changes, even though her ideas were constantly under siege. She strode British politics with great astuteness and had the knack of making the most of opportunities, a trait which made her the most admired, yet controversial leader of the UK.
