Owen was born in Bedwellty, Monmouthshire and went to Blaina Boys' Central School, which he left at the age of 13 to go to work in the local coal mines. However he was determined to better himself and in 1920 left work to study at the London Labour College. When his course ended he returned to Blaina to become a Tutor Organiser for the National Council of Labour Colleges, arranging for other local miners to attend further education courses.
Co-operative official
Already involved in Labour Party politics, in 1923 Owen was elected to Blaina District Council, on which he served for four years. In 1930 he moved to Leicester and became Secretary of the Leicester branch of the Independent Labour Party; he was elected to Leicester City Council in 1932. He then worked in the Co-operative movement, in the Education and Management section in Leicester, and from 1938 in the Education Office of Burslem Co-operative north of Stoke-on-Trent.
Political advancement
In 1940 Owen moved to London to work in the London Co-operative, followed four years later by transfer to Bristol. The nationalisation of the mines in 1948 led him to a job in the Community Office of the National Coal Board from 1948. He had further connections with the Co-operative movement. At this stage he was Labour candidate for Dover in the 1950 and 1951general elections.
Parliamentary career
Owen was chosen as Labour and Co-operative Party candidate for Morpeth at a by-election in 1954. This was a safe seat and Owen was duly elected. Owen remained a backbencher throughout his time at Westminster, although he did introduce a Private Members' Bill to regulate driving tests in 1966. He was allied with the left and wanted the British government to distance itself from the United States over the Vietnam war. For many years he served on the Estimates Committee, which gave him access to some secret information about government projects.
Secrets trial
A senior Czechoslovak intelligence officer, Josef Frolik, defected to the United States in 1969. He immediately named several British Labour MPs as having been friendly with Czechoslovak intelligence, including Owen. On 15 January 1970 Owen was arrested at his home in Carshalton, and charged with communicating information useful to an enemy. Bail was refused and Owen was held in custody until his trial at the Central Criminal Court in April 1970. Owen resigned his seat on 2 April by means of the Stewardship of the Manor of Northstead. At trial, it was established that Owen had received cash from Robert Husak, an intelligence officer at the Czechoslovak Embassy; he admitted receiving a regular envelope each month which sometimes contained £10, and sometimes £20. In return, Owen discussed political developments, but he denied ever passing on secret information, and the prosecution were unable to find any secret documents in his home. On 6 May, Owen was found not guilty on all charges.
Later life
Owen was partially rehabilitated as Chairman of Carshalton and WallingtonConstituency Labour Party from 1974. However, Frolik's memoirs portrayed him as a major agent. He gives Owen's codename as "Lee".
