Smith and his government initially continued to profess loyalty to Queen Elizabeth II. The 1965 Constitution reconstituted Rhodesia as a Commonwealth realm, with Elizabeth II as "Queen of Rhodesia". Indeed, the UDI document ended with the words "God Save The Queen". In December 1965, Smith, attempting to assert the rights he claimed as Her Majesty's Rhodesian prime minister, wrote a letter to Elizabeth asking her to appoint Dupont as governor-general of Rhodesia. The Queen rejected Smith's letter, which she characterised in her response as "purported advice". The UK, with the near-unanimous support of the international community, maintained that Gibbs was now Elizabeth II's only legitimate representative in what it still reckoned as the colony of Southern Rhodesia, and hence the sole lawful authority there.
