John Stanley, who has died aged 83, was one of the longest-serving postwar MPs, representing the Kent commuter belt constituency of Tonbridge and Malling for 41 years, but had a hapless reputation as a minister.Although he never became a cabinet minister, Stanley played a part in some of the most contentious issues of the Thatcher years.An ultra-loyalist, even before he became an MP he was one of the originators of the policy of selling council houses, and steered the legislation through the Commons as housing minister.Moved to the Ministry of Defence after the Conservatives’ post-Falklands general election landslide in 1983, he became embroiled in the Belgrano affair and the prosecution of the civil servant Clive Ponting.Some of these events may not have been his fault, but colleagues tended to believe that he made them worse by a seeming arrogance.

The Financial Times’s political editor Peter Riddell in a 1985 profile wrote that his problem was the lack of a sense of humour: “This, it is said, has reinforced both his pomposity and a fussy attention to minor details, which have infuriated officials.”Born in London, John was the son of Maud and Harry Stanley, who separated when he was a child, and he was brought up by his mother, a one-time secretary to Sir Winston Churchill.Educated at Repton school, in Derbyshire, he studied history at Lincoln College, Oxford, then at Syracuse University in the US, before going to work briefly for the Conservative Research Department, with responsibility for developing housing policy.After a year he became a research associate at the International Institute for Strategic Studies, the defence and security thinktank, and then a financial analyst at the mining corporation Rio Tinto Zinc, a post he would hold for 10 years until becoming a minister.He fought the safe Labour seat of what was then Newton in Lancashire in the 1970 general election before being eventually selected as the candidate for Tonbridge and Malling at the February 1974 poll, where his Labour opponent was Jack Straw, similarly going through the rite of passage of fighting an unwinnable seat.

He held the constituency, generally with majorities above 10,000, through nine further general elections until his retirement in 2015.Recognising a kindred spirit, Margaret Thatcher chose him as one of her parliamentary private secretaries in 1976.It was Stanley, in tears, who had to inform her of the assassination of her close political associate Airey Neave shortly before the 1979 election.Neave had been blown up in his car by a bomb placed by the IRA as he drove out of the Commons MPs’ carpark and Stanley had been the first on the scene.Appointed minister of state for housing and construction in Thatcher’s first administration, allegedly partly to keep an eye on Michael Heseltine as environment secretary, Stanley piloted the sale of council housing on to the statute book, despite the opposition of Labour councils.

Regarded then by the Tories as a signal triumph, with half a million sales in its first four years, the effects of the policy in reducing the stock of local authority housing are less praised today.At the time, though, Stanley was earmarked as a coming man, “one of us” and a future star.After the 1983 election victory, he moved with Heseltine to the Ministry of Defence as armed forces minister where, as at Environment, he was unpopular with civil servants, going through, in Riddell’s words, a remarkably high turnover of private secretaries and becoming the butt of a number of stories of his maladroitness.These included the time he got stuck in a lift at the MoD and insisted that not only should files be passed to him through a chink in the lift door while he waited to be freed, but that his superiors must be informed immediately of his plight; Heseltine allegedly said he would indeed like to be informed so he could go along and have a laugh.There was also the time on a Nato trip to Iceland when Stanley demanded an RAF sniffer dog should be sent from Britain to check that there was not a bomb on his plane.

There wasn’t, and the dog had to be placed out of action in quarantine for six months as a result,Much more serious was the case of Ponting, who leaked details of the sinking of the Argentinian battleship Belgrano during the Falklands war to the Labour MP Tam Dalyell, showing that ministers knew the ship was sailing away from the British invasion force, not towards it, as was publicly claimed by Thatcher,Ponting disclosed that Stanley had argued that ministers under pressure from Dalyell in the Commons should say incorrectly that the information was classified – misleading MPs being a serious offence,Ponting was tried under the Official Secrets Act and acquitted,Stanley survived that debacle, but was moved following the 1987 general election, again to be a minister of state, but in the Northern Ireland Office under Tom King, another secretary of state untrusted by the prime minister.

There too he was mocked for sticking inside the government headquarters at Stormont Castle rather than venturing out and, bizarrely, for unsuccessfully demanding the demolition of a house on security grounds next to traffic lights where he had been delayed.His decision to allow a teenaged soldier, Private Ian Thain, convicted of shooting an unarmed man in Belfast in 1983, to return to service after serving just three years of a life sentence, was also controversial.Within a year Stanley was sacked as a minister and given a knighthood for his services to the Northern Irish peace process.Thereafter Stanley became a long-serving member of the parliamentary select committee on foreign affairs (1992-2015) and a member of the Nato parliamentary assembly.He also held directorships and served as a trustee of ActionAid.

He married Susan Giles in 1968.The couple had two sons and a daughter and were divorced in 2005.The following year he married Elizabeth Brooks (nee Tait).His eldest son died in 2000.Stanley is survived by Elizabeth, and his two children.
