November 22nd. is the anniversary of the fall of Margaret Thatcher as Prime Minister, one of the most dramatic political events of modern times. Relive the events, and in particular the extraordinary speech by Sir Geoffrey Howe in the Commons, in this video on the Youtube site. Anyone who doubts the significance of parliament will see here its seminal importance as the arena in which the most formidable British leader since Churchill met her doom. Thatcher never recovered from the Howe speech, or the loss of confidence and credibility that it engendered amongst her parliamentary colleagues. Its immediate consequence was a leadership challenge from Michael Heseltine, which ultimately resulted in Thatcher's forced resignation; "treachery, with a smile on its face".
