Edexcel’s AS topic, 'British Political History 1945-1990: Consensus and Conflict' covers many governments, all of which are possible subjects of controversy, but none more so than that of the Iron Lady. Following the release of 'The Iron Lady' film in cinemas, Geoff Stewart looks at the premiership of Margaret Thatcher, discussing why she is such a controversial figure, and why arguments rage among politicians and historians about her legacy.
