By the late 1970s, he was involved in
Conservative Party politics and the
Centre for Policy Studies think-tank. He wrote speeches for
Archie Hamilton MP, a friend from Eton. He was a controversial and was instrumental in organising and funding the anti-strike campaign in the coalfields, including funding a breakaway miners union, the
Union of Democratic Mineworkers (UDM). His involvement in aiding working miners extended to employing former members of the
SAS to protect the families of working miners and using the resources of 'the secret state'. Hart's involvement was eventually a source of bitterness for the UDM's leader
Roy Lynk. and which had used "anti-gay material during their anti-Labour campaign
in 1987". In 1988 he played a leading role in mobilising young activists against pro-
devolution dissidents at the
Scottish Conservative and Unionist Party conference in
Perth, Scotland. Towards the end of
Hungarian socialism, Hart channelled support from the West to the fledgling
Fidesz party, which at the time was an unofficial anti-Communist student movement developing at the
Eötvös Loránd University under the protection of the last Communist minister of the interior,
István Horváth. The group received a visit and material support from
George Soros by 1985. It was formally founded in 1988, changed into a party in 1989, and by 1990 its members were part of Hungary's new parliament. In the autumn of 1993, he was appointed as a personal advisor to
Malcolm Rifkind,
Secretary of State for Defence, a position Hart retained when
Michael Portillo succeeded Rifkind. Reportedly a long-standing Portillo contact, Hart is credited with writing the 'Who Dares Wins' conclusion to Portillo's 1995
Conservative Party Conference speech. He was also involved in the 1995 plan to install 40 telephones and fax machines in a Lord North Street house for a Portillo leadership challenge to Conservative leader and prime minister
John Major which never emerged. In the 2000s he was involved in the international
defence industry – including being a lobbyist for
BAE Systems and
Boeing. In 2004 an
arrest warrant for Hart was issued concerning his alleged involvement in that year's
coup attempt in Equatorial Guinea. via Defence Consultancy Ltd, an anonymously registered company based in the
British Virgin Islands. While BAE was under investigation for
corruption at the time, Hart was not thought to have done anything illegal. == Cultural depictions ==
