Roger Edward Windsor (born 8 January 1945) was chief executive of the National Union of Mineworkers (NUM) between 1983 and 1989, including during the 1984 miners' strike.
Windsor was accused of damaging the image of the union by visiting Libya during the strike and meeting Colonel Gaddafi, at the time an enemy of the United Kingdom.
Both Mick McGahey, vice president of the NUM, and Peter Heathfield, general secretary, denied knowing about this trip before it was revealed in the press.
For reasons still not clear, Windsor met Colonel Gaddafi and film of the two men embracing was shown on British TV.
[6] The head of the MI5 branch responsible for 'monitoring' unions and strike activity at the time of the strike, Dame Stella Rimington, gave an unusual denial in 2001, saying that Windsor was "never an agent in any sense of the word that you can possibly imagine", and, in breach of normal government protocol, John Major, the Prime Minister, made an official statement that Roger Windsor was never involved with the government.
At the time of the miners strike, he had lived on Lower Street in Stroud for five years, with his wife Angela and his three children.
