Tom Wilson was enrolled as a police constable in 1932. He was based (as I recall) in Kentish Town and was on duty at the Battle of Cable Street on 4th October 1936, when a huge crowd of anti-fascists prevented Oswald Mosley and his black shirt followers from marching through London's main Jewish quarter. I interviewed him in September 1986 as part of a radio feature I made about the fiftieth anniversary of Cable Street - I also spoke to both communists and fascists who were present. Wilson also reflects widely on public order issues in London in the 1930s and mentions in passing the hunger marches and the Berlin Olympics which he attended.
As I recall, at the time I interviewed him, Tom Wilson ran a small hotel in Sussex Gardens, Paddington.
