Barker was elected to the
Western Australian Legislative Assembly at the
1939 state election, winning the seat of
Irwin-Moore as an independent. He resigned from parliament on 2 August 1939 without taking his seat, shortly before he was due to be sworn in as a member. In September 1940, Country Party MP
Lindsay Thorn alleged under
parliamentary privilege that Barker had an extensive criminal record in New Zealand prior to moving to Australia and had in fact been ineligible to serve as a member of parliament. Thorn had received a letter from New Zealand detailing that a man with the same name as Barker had been convicted of various offences in the late 1910s and early 1920s, including theft and
cheque fraud, and had served over three years in prison. ==Personal life==
