One American innovation that was swiftly adopted by the Conservatives was the use of computers to target and contact potential voters in marginal constituencies
Party Chairman Cecil Parkinson organised a direct mail campaign that reached 500,000 voters before the 1983 general election
The social makeup of the Conservative Party changed more rapidly under Thatcher than in the years before 1979
Although most MPs still went to university, the party became less posh
The proportion of MPs educated at public schools dropped from 75% to 66% between 1974 and 1987
There were more self-made businessmen and fewer men of inherited wealth
Thatcher is fairly accused of doing little to advance women in politics
During her time as PM, the no. of female MPs only increased from 19 to 41
She believed that merit alone should lead to a successful political career and was opposed to any form of positive discrimination in favour of women
Thatcher's determination to drive forward with policies she believed to be right ultimately led to her downfall in November1990
By 1990, she had alienated a long list of Conservative, 'big beats', who were unhappy at being ignored or even rebuked in cabinet
Tow of the most senior to be handbagged were Chancellor Nigel Lawson (resigned Oct 1989) and Deputy PM Geoffrey Howe
