"It's a performance of towering proportions that sets a new benchmark for acting."

The film follows Baroness Thatcher from her early years breaking through class and gender barriers to become prime minister to her political downfall in 1990.

The Iron Lady also stars Jim Broadbent as her husband Denis Thatcher and Richard E Grant and Anthony Head as cabinet ministers Geoffrey Howe and Michael Heseltine.

The Thatcher era from 1979 to 1990, was a time of social and economic change for Britain.

Elected following a period of widespread strikes, dubbed the winter of discontent, Lady Thatcher and her Conservative government embarked on tough reforms to tackle inflation and the trade unions.

Her policies divided the country - seeing a boom in the service sector and home ownership but a decline in manufacturing and soaring unemployment.
