text: MI5 covered up the sexual abuse of boys in the notorious Kincora home, a former Army Intelligence officer claimed last night. Brian Gemmell, a former captain in the Intelligence Corps, said spy chiefs ordered him to ‘stop digging’ when he reported a possible paedophile ring at the Northern Ireland children’s’ home. He spoke out during a meeting with victim Richard Kerr, who claimed he was one of three youngsters trafficked from the home before being molested by ‘very powerful’ figures in a Westminster paedophile gang. Scroll down for video . Brian Gemmell, a former captain in the Army Intelligence Corps (pictured), said MI5 spy chiefs ordered him to ‘stop digging’ when he reported a possible paedophile ring at the Northern Ireland children’s’ home, Kincora . He claimed he was sexually abused by politicians and other senior men at Dolphin Square apartment complex in Pimlico and Elm Guest House, in Barnes, west London, which are being investigated by Scotland Yard amid ‘credible’ claims a Tory MP murdered a young boy. Campaigners claim Mr Kerr’s account provides a clear link between VIP paedophile rings in London and Belfast. MI5 has faced long-standing allegations of covering up child abuse to enable it to gather intelligence on Loyalist politicians during the Troubles. But it has also been accused of not acting to protect leading Establishment figures involved in the crimes. Mr Gemmell, who served in military intelligence in Belfast, presented a report on allegations of abuse at Kincora to a senior MI5 officer in 1975 but to his astonishment was told to quit his probe. Speaking to Mr Kerr on Channel 4 News, he said: ‘That’s the thing that hits me - that if I really pushed the thing through, you could have been rescued. I’m sorry.’ His revelations will strengthen calls for the allegations about the Irish children’s home to be covered by the judge-led abuse inquiry announced by Home Secretary Theresa May. The inquiry will investigate whether public bodies, including governments, charities, the Church and BBC, failed to protect children. It was set up amid claims a child sex gang operated in Westminster in the 1980s. The investigation into historical abuse, which will be led by New Zealand High Court judge, Justice Lowell Goddard, is likely to be able to study files held by MI5. Mr Gemmell said: ‘I think Richard’s transporting over to the United Kingdom mainland to be abused, rather than just being abused in Northern Ireland, speaks volumes. It ties the two together.’ Mr Gemmell met with victim Richard Kerr, who claimed he was one of three youngsters trafficked from Kincora (pictured) before being molested by ‘very powerful’ figures in a Westminster paedophile gang . Speaking to Channel 4 News, Mr Kerr, who now lives in Dallas, Texas, said he and two other boys suffered abuse at Kincora in the mid-1970s before being trafficked to London in 1977, where they suffered further abuse. Boys - many in local authority care - are alleged to have been abused by figures including the late Liberal MP Cyril Smith, Cabinet ministers, clergymen, pop stars, spies, judges and members of the royal household. MI5 has been accused of suppressing allegations of child abuse against the politician, who died in 2010, when they were made during the 1960s, 1970s and 1980s. The Kincora children’s home in east Belfast was run by William McGrath, the head of an extreme Protestant loyalist group called Tara and an alleged MI5 informant. He and two other members of staff – William Semple and Joseph Mains – were jailed in 1981 for sexually assaulting boys in their care. In February, lawyers for victims challenging the refusal to include Kincora in Justice Goddard’s wide-ranging inquiry told the High Court in Belfast that MI5 was aware of the abuse but allowed it to continue to protect those responsible from prosecution.
