Labour leader Ed Miliband praised Baroness Thatcher for "breaking the mould".
“At each stage of her life she broke the mould - a woman at Oxford, when there was no a single woman in the university who held a full professorship.
"A woman chemist when most people assumed scientists had to be men, a woman candidate for Parliament in 1950 against the opposition of some in her party in Dartford at the age of only 24, a woman MP in 1959 when just 4% of MPs in the whole of this House were women."
