During this period it was alleged that Morrison joined the small group of MPs, who included Michael Grylls and Neil Hamilton, who took money from Ian Greer on behalf of third-party clients.[5] During the Cash for Questions Inquiry, Ian Greer Associates admitted Morrison received payments after ceasing to be an MP. The Parliamentary Report in Hansard quotes Ian Greer as stating he made "Two commission payments, perhaps three, for client referrals" to Morrison between 1993 and 1994.[6]
In 1990, Morrison became Parliamentary Private Secretary to the Prime Minister, Margaret Thatcher; he was the leader of her campaign team in the Conservative leadership election in the same year.[citation needed] He was relaxed about Thatcher's prospects and predicted an easy win for her. Alan Clark went to visit him one afternoon during the campaign and found him asleep in his office. Morrison claimed that he had assurances from enough MPs that they were Thatcher supporters to be certain she would win.[citation needed]
After the first ballot of Conservative MPs had shown that Thatcher did not have enough votes to win outright, Morrison suggested to her that she should consult the Cabinet one-by-one to gauge support. He said to her: "Prime Minister, if you haven't won then there are a lot of Tory MPs who are lying".[7] He stood down at the 1992 general election, being succeeded as MP for Chester by Gyles Brandreth.
Morrison was knighted by Queen Elizabeth II in February 1991.[8] He died of a heart attack early in the morning of 13 July 1995, aged 51.
There were no very precise allegations, but suggestions that Morrison might have attended gay parties and engaged in casual pick-ups ... Morrison was asked by whips about the accusations and always categorically denied them ... [Norman] Tebbit recalled, 'I began to hear allegations, coming from his constituency [Chester], when he was with me at CCO, that he was excessively interested in schoolboys. I faced him. He swore absolutely that there was no truth in it. I wasn't absolutely convinced.' Tebbit did not discuss the rumours with Mrs Thatcher, however, and she never raised them. The only effect of such stories was that an informal ceiling was put on Morrison's career. He was known to want to be chairman of the party after the 1987 election, but it was understood that this would be too risky. Robin Butler recalled that, in his time as Mrs Thatcher's private secretary, which ended in 1985, no accusations came up about Morrison. When Butler became Cabinet secretary in 1987, however, allegations did surface. They were about homosexuality, and therefore the possibility of being compromised by Soviet agents, rather than about child abuse.[11]

Between 1974 and 1990, up to 650 children from forty children's homes (such as Bryn Estyn in Wrexham) were sexually, physically and emotionally abused. Richards said that Morrison and another high-profile Conservative politician were named in documents as regular and unexplained visitors to the care homes.[citation needed]
Former Conservative minister Edwina Currie stated that Morrison regularly had sex with 16-year-old boys at a time when the legal age of consent for same-sex relations was 21.[14] In 2002, Currie wrote in her autobiography that "he's what they call 'a noted pederast', with a liking for young boys; he admitted as much ... when he became deputy chairman of the party but added, 'However, I'm very discreet' — and he must be!"[14]
Gyles Brandreth, Morrison's successor as MP for Chester, said that he was told by multiple constituents that Morrison was "a disgusting pervert" and a "monster".[15]
In July 2014, Barry Strevens, a former bodyguard to Margaret Thatcher, claimed that he warned her that Morrison allegedly held sex parties with underage boys.[16] Despite his passing on the allegations to Thatcher, Morrison was promoted later to the position of deputy chairman of the Conservative party.[16] Thatcher's parliamentary private secretary, Archie Hamilton, reportedly took notes of what was said.[16] Strevens reflected: "I am sure [Hamilton] would have given her assurances about the rumours, as otherwise she wouldn't have given him the job."[16]
In January 2015, The Daily Telegraph reported allegations that Morrison raped a 14-year-old boy at Elm Guest House in London. The alleged victim said he was walking in the village of Harting in West Sussex in 1982, when Morrison gave him some money and later lured him to London.[17]
In 2019, Morrison was investigated by the Independent Inquiry into Child Sexual Abuse (IICSA), with evidence from Eliza Manningham-Buller (a former director general of MI5), who had been friendly with Morrison for a time. Manningham-Buller said that she may have provided the cabinet secretary with information including the comment that Morrison had a "penchant for small boys".[18]
In February 2020, the Independent Inquiry into Child Sexual Abuse claimed senior officials within the Conservative Party knew about allegations concerning Morrison for years but did not pass them on to police.[19]
