A long-time member of the
National Party, he was secretary of the
Mundubbera branch from 1965 until his election as president in 1967, serving until 1970. In 1974, he was elected to the
Queensland Legislative Assembly as the member for
Isis. Promoted to the front bench as
Minister for Education in 1982, he was briefly Leader of Government Business in the House in 1987 before being elected
Speaker in December, immediately after
Joh Bjelke-Petersen's ousting by
Mike Ahern. On 3 May 1989, Powell resigned from the National Party and declared himself an
independent. He continued as Speaker until 5 July 1989, when the government voted against him on a matter of privilege; his resignation prompted scenes of chaos in the chamber. He remained a Member of Parliament until his sudden resignation on 31 July 1989; he was urged to form a new Conservative Party but declined. He ran for Isis as an independent at the
1989 election, but without success. ==References==
