At Westminster, Bell became the Parliamentary Private Secretary to the Deputy Leader of the Opposition Roy Hattersley in 1983. He was promoted to the shadow frontbench in 1984 by Neil Kinnock as a Spokesman for Northern Ireland. However, he chose to resign his post after the Cleveland child abuse scandal which occupied two years of his life, after making unsubstantiated accusations of 'clinical error' against local paediatricians and child sexual abuse specialists. The paediatricians, Dr. Marietta Higgs and Dr. Geoffrey Wyatt, were later absolved and their forensic clinical work validated at a committee of inquiry overseen by Dame Elizabeth Butler-Sloss.
