John Nettleton, who has died aged 94, was a prolific character actor for more than half a century. He was admired for the dozens of classical supporting roles he took on stage, but he gained his greatest recognition on screen. His comic flair was best exploited as the cold, calculating Sir Arnold Robinson in the TV sitcom Yes Minister (1980-84), set in the corridors of Whitehall.
Although his presence and resonant voice invested authority in the characters he played, Nettleton was shy and totally unstarry. He described himself as a “workman” actor, adding: “I’ve got a pipe-smoking image. I’m typed as a senior civil servant, a soldier, a judge, a Harley Street doctor.”
Yes Minister, the biting political satire created by Antony Jay and Jonathan Lynn, cast him to type as the cabinet secretary, a scheming bureaucrat who manipulates Jim Hacker (played by Paul Eddington), the minister in the fictional Department of Administrative Affairs, through his permanent under-secretary, Sir Humphrey Appleby (Nigel Hawthorne).
By the time Hacker has risen to the top job in government in the sequel, Yes, Prime Minister (1986-88), Sir Arnold has retired and become president of the Campaign for Freedom of Information.
Television fame came to Nettleton after three decades on stage that began with Shakespeare performances in Stratford-upon-Avon, followed by a string of West End roles and plays with the National Theatre company. He was also singled out for credit as, according to Peter Hepple of the Stage, a “jovially pandering” Polonius bringing humour to an acclaimed Prospect theatre production of Hamlet at the Old Vic (1977-78), featuring Derek Jacobi in the title role.
Nettleton was born in Sydenham, south London, to Alfred Nettleton, a factory supervisor, and his wife, Dorothy (nee Pratt). On leaving St Dunstan’s college, Catford, he trained at Rada, graduating in 1951 and making his professional debut with a walk-on role in the pantomime Snow White at St James’s theatre, London. He then joined the Shakespeare Memorial Theatre company (1952-53), taking small roles in Stratford-upon-Avon and on a 1953 tour of Australia and New Zealand.
He married the actor Deirdre Doone (born Anne Cooper) in 1954 after appearing with her on an Elizabethan Theatre tour. He then broke into the West End, with roles such as the police superintendent Mr McBryde in A Passage to India (Comedy theatre, 1960).
Peter Hall, who directed Nettleton in several London productions, signed him as a contract player when he formed the Royal Shakespeare Company. Nettleton spent five years (1961-66), mostly at the Aldwych theatre, London, in supporting roles that included the surgeon Mr Mannoury in The Devils (1962) and Friar Barnardine in The Jew of Malta (1964).
With the National Theatre company the following decade, he played Jaques on a North American tour of its all-male production of As You Like It that included a run on Broadway (Mark Hellinger theatre, 1974), with Hawthorne playing the clown Touchstone.
Away from classical roles, he was at his comic best in the role of (Roy) Jenkins, Margaret Thatcher’s butler, in John Wells’s farce Anyone for Denis? at the Whitehall (now Trafalgar) theatre (1981-82).
Nettleton and his wife teamed up to take Raymond Briggs’s stage version of his anti-nuclear story When the Wind Blows on tour (1984-85). Both CND members themselves, they played the elderly couple Jim and Hilda Bloggs, based on the writer’s own parents, who trust in “the authorities” in the aftermath of a nuclear attack. Later, Nettleton played the magistrate in the 1990 National Theatre production of Alan Bennett’s Wind in the Willows adaptation.
He brought authority to the role of Arthur Kipps, the storyteller, in Stephen Mallatratt’s thriller The Woman in Black for two runs at the Fortune theatre (1992-93 and 1999).
Although he appeared on television throughout the 1950s, the first screen role that brought Nettleton to the attention of critics was Charles, a principled business executive whose wife walks out on him, in John Hale’s play The Noise Stopped for ITV’s Armchair Theatre series in 1966. One critic remarked on his similarity to Alec Guinness – “the deliberate speech, the apparent under-playing, the suggestion of fire beneath the ice”.
Nettleton continued popping up in character roles on TV. He had five different parts in Z Cars between 1962 and 1977, three of them as detectives, and was Francis Bacon in Churchill’s People (1975) and the lord chamberlain in Henry VIII (1979).
He also played military types – a major in The Flame Trees of Thika and the commanding officer of Charles Ryder (Jeremy Irons) in Brideshead Revisited (both 1981) – and was the father in the coming-of-age television play East of Ipswich (1987), written by Michael Palin, and an Oxford vicar turned into an ape in the 1989 Doctor Who adventure Ghost Light.
The talent for comedy he demonstrated in Yes Minister led him to be cast in a string of sitcoms. He played Arthur Spender, one of the bosses of a fading ad agency who discovers the natural talents of his secretary (Leslie Ash) for spotting successful products and dreaming up slogans, in The Happy Apple (1983). He then played Lord Mountfast, who becomes the husband of Isobel (Gail Harrison), daughter of the self-made mill and mine owner Bradley Hardacre (Timothy West), in the second series of Brass (1984) and had a guest role as a vicar in Victoria Wood: As Seen on TV in 1985.
Nettleton brought elements of his Yes Minister character to the second run of Fairly Secret Army (1986) as Smith, a shady government figure using to his own advantage the rightwing group formed by a retired major (Geoffrey Palmer) to defend the country against ideological threats, and The New Statesman (1987-89) as Sir Stephen Baxter, an anti-pornography Conservative MP leading the Campaign for Moral Regeneration.
He is survived by his wife and their three daughters, Sarah, Joanna and Jessica.
