Roger Windsor was chief executive of the National Union of Mineworkers (NUM) between 1983 and 1989, including during the 1984 miners' strike. He later moved to France and then to Herefordshire.
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. Windsor was despatched to Libya by Arthur Scargill, possibly in an attempt to put NUM funds beyond the reach of the Government. Both Mick McGahey, Vice President, 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 Gadaffi and film of the two men embracing was shown on British TV. The Sunday Times' report on his visit was credited by some with substantially undermining public and parliamentary support for the miners.
In 1990, Windsor was involved in media reports concerning Arthur Scargill's misuse of union funds and receipt of funds from Libya, allegations which were substantially based on Windsor's evidence. The story was initially reported on the front page of the Daily Mirror and in the Central TV programme The Cook Report. Gavin Lightman QC was requested to undertake an enquiry into the manner in which NUM funds and the £1 million donation by Russian miners were used during and after the miners' strike and found that Scargill had failed to account properly for substantial amounts of money including bank accounts opened in the name of Scargill's mother and Nell Myers (Scargill's PA). The Report also found that Windsor had not repaid the £29,500 that he had admitted taking from the Miners' Solidarity Fund.
Then Mirror editor Roy Greenslade later wrote an article apologising to Scargill for the false claim that he had used Libyan money to pay off his mortgage and for relying on Windsor as a source, given that Windsor had still not repaid the £29,500 as of 2002, when the highest court in France ordered that he repay the money.
