Dr Qwominer William Osborne, OBE (usually referred to as Q.W. Osborne or William Osborne) was a politician and physician in the British Virgin Islands. Although Dr Osborne never became head of state in the British Virgin Islands, he came as close as a person reasonably could without attaining that goal.
His political career started in the 1963 general election, when he was elected to the seat for the 5th District. Prior to 1967 elections to the Legislative Council of the British Virgin Islands were on a non-party basis, and legislators who were elected governed collectively.
However, the 1967 general election introduced party politics into the British Virgin Islands, and Dr Osborne founded and became leader of the VI Democratic Party. Ultimately that party would come second in the election to the BVI United Party led by Lavity Stoutt. Dr Osborne thereby became the first ever Leader of the Opposition in the British Virgin Islands.
In the subsequent 1971 general election led his party to the highest number of overall seats, but short of an outright majority. Faced with potentially ruling as a minority government, he formed a coalition with independent candidate Willard Wheatley. However, Wheatley required that he be made Chief Minister, and Dr Osborne agreed. Dr Osborne was appointed Minister for Natural Resources and Public Health.
