An account in The Times of his candidature described him in the following terms: "He is a bachelor solicitor, aged 29, wearing his public school manner as prominently as his rosette.
Gow was brought onto the Conservative front bench in 1978 to share the duties of opposition spokesman on Northern Ireland with Airey Neave.
The two men developed a Conservative policy on Northern Ireland which favoured closer ties with Great Britain in order to further integrate the region.
In late-1983, he developed plans with Alan Clark to reinvigorate Thatcher's private office by expanding it and its influence over policy, thereby creating a new role for himself; but these came to nothing.
"After taking what was perhaps too principled a stand in a complex dispute over Housing Improvement Grants, he was moved sideways to the post of minister of state at the Treasury".
In November 1985, Gow was persuaded by the speeches of his cousin Nicholas Budgen to resign as Minister of State in HM Treasury over the signing of the Anglo-Irish Agreement.
[15][16] Despite his disagreement with government policy, he used his resignation speech to underline his personal devotion to Thatcher, describing her as "the finest chief, the most resolute leader, the kindest friend that any member of this House could hope to serve.
"[17] The Anglo-Irish Agreement would ultimately lead to devolved government for Northern Ireland, power sharing in the province and engagement with the Republic.
He was a leading opponent of any compromise with republicans and his tactics in this regard caused concern to the Northern Ireland Secretary Jim Prior and other MPs.
According to The Guardian: "He [Gow] co-ordinated the Tory backbench opposition to Mr Prior's Northern Ireland Assembly bill in the early 1980s.
In his speech, Gow referred to a letter he had received from a firm of consultants who had offered to improve his personal appearance and television image, making a few self-deprecating jokes about his baldness.
In spite of his disagreement with the direction in which Government policy on Northern Ireland was moving, Gow remained on close terms with Thatcher.
[24] In the early hours of 30 July 1990, a bomb was planted under Gow's Austin Montego car, which was parked in the driveway of his house in Hankham, near Pevensey in East Sussex.
[14][25] The 4.5 lb (2.0 kg) Semtex bomb detonated at 08:39 as Gow reversed out of his driveway, leaving him with severe wounds to his lower body.
[28] Upon hearing of Gow's death, Labour Party leader Neil Kinnock commented, "This is a terrible atrocity against a man whose only offence was to speak his mind....
[30] The IRA claimed responsibility for killing Gow, stating that he was targeted because he was a "close personal associate" of Thatcher and because of his role in developing British policy on Northern Ireland.
