Harry Kissin's wikipedia article

 Harry Aaron Kissin, Baron Kissin (23 August 1912 – 22 November 1997) was a British businessman and life peer.

Kissin was born in Danzig, the son of a Russian Jewish grain merchant. He was educated in Danzig and at the University of Basel, where he gained a doctorate in law. He qualified as a lawyer in Switzerland in 1933, but moved to London the same year.

A close friend and confidant of Harold Wilson, Kissin was made a life peer on 27 June 1974 as Baron Kissin, of Camden in Greater London. Although he was known to be a Labour supporter, he sat as a crossbencher in the House of Lords.

In 2009, it was revealed that Kissin's name had appeared on a MI5 list of Wilson associates who were considered suspicious because of their links with Eastern Bloc countries. Additionally, MI5 considered Kissin untrustworthy because of his use of prostitutes, and asked the Cabinet Secretary to inform Wilson that Kissin was "obviously not a man to be trusted with confidences".
