opponents of Margaret Thatcher have praised her "remarkable achievement" in becoming the UK's first – and so far only – female Prime Minister.

Labour politicians lined up to pay tribute to the former Conservative leader for gaining the keys to No 10.

Mrs Thatcher herself famously predicted there would not be a female Prime Minister in her lifetime.

Subsequent generations of female politicians said her achievement had served as an inspiration.

Dame Anne Begg, the Labour MP for Aberdeen South, said: "For me, she showed that it was possible to be both a woman and Prime Minister. It was an amazing achievement."

Yvette Copper, Labour's Shadow Home secretary, stated: "Politics aside, it was remarkable achievement to become Britain's first woman Prime Minister."

Others were also critical of Lady Thatcher's politics, but still felt she deserved praise for her achievements.

Caroline Flint, Labour's shadow energy secretary, used Twitter to say: "Lots I didn't agree (with) but credit where it's due Mrs Thatcher defied the odds to become Tory Leader and most successful female politician."
