David Ranson

David Ranson was a senior officer of the Security Service, MI5.

Stella Rimington states in her autobiography that she succeeded Ranson as a Deputy Director General of MI5 in 1990:

I was appointed on the retirement of David Ranson a long-time Security Service officer who had made his reputation in the counter-subversion branch at the time of the 1974 miner's strike and had been very involved in the early days of the service's work fighting international terrorism. His retirement turned out to be sadly short, as he died only a couple of years later.
