Trial and death
Ward's committal proceedings began on 28 June, at Marylebone magistrates' court, where the Crown's evidence was fully reported in the press. Ward was committed for trial at the Old Bailey but was released on bail pending trial. In his account of the trial, which began on 22 July, Richard Davenport-Hines describes it as an act of political revenge: "The exorcism of scandal in high places required the façade of [Ward's] conviction on vice charges". While living with Ward, Keeler and her fellow model Mandy Rice-Davies had made small contributions to household expenses, and had repaid money lent to them by Ward. The thrust of the prosecution's case, in which Keeler and Rice-Davies were their principal witnesses, was that these payments indicated that Ward was living off their earnings from prostitution (and was thus a pimp). Ward's approximate income, from his practice and from his portraiture, had been around £5,500 a year, a substantial sum at that time (equivalent to £103,000 in 2025). However, one of the police officers involved in the investigation, Sergeant Arthur Eustace, stated that "Ward had no money in his British bank account" at the time, and that they could find nothing to indicate that he had been living off "immoral earnings". Despite being a prosecution witness, Rice-Davies "truculently tried to testify ... on behalf of the defendant", arguing that "you might as well prosecute every bachelor in London."
The prosecution case looked weak, but Ward's perceived image had been tarnished in the committal proceeding. None of his well-known friends offered to speak on his behalf, and MI5 did not reveal the uses they had made of Ward as a channel of communication to the Soviets. The prosecuting counsel, Mervyn Griffith-Jones, who adopted a tone of moral outrage, "pronounc[ing] words like 'prostitute', 'pimp', and even 'sexual intercourse' with obvious distaste", portrayed Ward as a man who represented "the very depths of lechery and depravity", and described him as "a thoroughly filthy fellow", while the judge, Sir Archie Marshall, adopted a similarly hostile attitude. Ward was represented by James Burge, who described Griffith-Jones as somebody who could "make even a honeymoon sound obscene."
Towards the end of the trial, information relating to another case, in which Keeler had been a leading witness, was revealed by the Court of Appeal. This indicated that Keeler's evidence in that earlier case had been false. Marshall did not reveal the salient fact to the Ward trial jury that the reliability of the prosecution's chief witness had been compromised, and invited the jury to disregard the appeal court's decision.
On 30 July, Marshall began his summary in a speech which was so damning that Ward despaired. That evening, after writing numerous letters to friends and to the authorities, Ward took an overdose of sleeping tablets and was taken to hospital. The next day, Marshall completed his summary and the jury found Ward guilty in absentia on the charges of living off the earnings of prostitution, while acquitting him of several other counts. Sentencing was postponed until Ward was fit to appear, but he died on 3 August.
On 9 August, a coroner's jury ruled Ward's death as suicide by barbiturate poisoning. According to reports, Ward left several notes, one of which read, "I'm sorry to disappoint the vulture ... I feel the day is lost. The ritual sacrifice is demanded and I cannot face it". On the day of the inquest, after a private memorial service at the chapel in St Stephen's Hospital, Ward's remains were cremated at Mortlake Crematorium. "Though his solicitor had asked that no flowers be sent, there was a wreath of two hundred roses from, among others", English playwrights John Osborne and Arnold Wesker, theatre critic Kenneth Tynan, writers Angus Wilson and Alan Sillitoe, and musician Acker Bilk, "who later withdrew his name". "With the flowers came a note: “To Stephen Ward, victim of British hypocrisy.”" Tynan stated that "British society created him, used him, and ruthlessly destroyed him. The Establishment has closed its ranks around its body."
In their accounts of the security aspects of the Profumo affair, Anthony Summers and Stephen Dorril provide extra information concerning Ward's last hours, his movements and his visitors. They also quote from an interview with "a former MI6 operative", who asserted that Ward had been murdered by an agent working on behalf of MI6. The main motive for the killing was Ward's ability to embarrass the government and the royal family. The method, apparently, was to encourage Ward to continue to take barbiturates until a fatal dose had been ingested. The reporter Tom Mangold, one of the last to see Ward alive, dismisses the murder theory, while allowing that there are unexplained circumstances relating to Ward's death.
