[2012 May] Tony Blair – The Return of the Prodigal Son By T Stokes A similar chain of events had occurred nearly 30-years earlier when the then Labour leader Hugh Gaitskell died after visiting the Soviet embassy in January 1963. Like John Smith and Robin Cook, Gaitskell was a fit man in his fifties with no prior record of heart problems. Nonetheless, a sudden and unexpected heart attack killed Gaitskell and conveniently opened the way for Harold Wilson; which pleased the Soviets as his policies played right into their hands, and led to suspicions of foul play as like John Smith, Gaitskell was poised to become prime minister. The Porton Down disease specialist, Dr. Ladell later secretly reviewed Gaitskell’s death and concluded that he was indeed probably murdered.
He would also claim while drunk at whites club, that the labour leader Hugh Gaitskell was murdered by the Soviets. Years later, Gaitskell's family nanny, a woman of scrupulous integrity, Maude Burton, said the family believed it also. I read her actual statement, before official alteration and signing. The family nanny was then retired to a tiny village called Brancaster Staithe, where she was born, given a cottage, and sworn to secrecy.  The Mystery of Super Spy - Sir Anthony Blunt by T. Stokes
