Whistleblowers alleged that Margaret Tatcher personally authorized a „Get Scargill“ campaign during and after 1984-85 strike and ordered an unprecedented mobilization of British and American electronic surveillance networks .
There had been direct media campaign against the miners` leadership. In December 1991 Stella Rimington became first director-general of MI5 whose appointment would be publicly disclosed by the most secretive government bureaucracy in the Western world. She headed the department in charge of monitoring the trade-union movement at the time of its greatest industrial conflict with Tatcher`s government.
Former Labour Secretary, Merlyn Rees, supported Tam Dalyell who tabled the House of Commons motion calling for a statement on Tatcher`s activities.
