In his early life, Watts served as an aircraftsman in the Royal Air Force. He later became a member of the British Union of Fascists in the 1930s and was an active recruiter. With the outbreak of the Second World War, he was arrested and interned under Defence Regulations and held first at Brixton Prison, and afterwards at Camp 020 at Latchmere House. He was moved to Ascot internment camp in Berkshire, where he became the unofficial camp leader, producing a newspaper titled The Flame and negotiating with the camp authorities on behalf of the inmates.
