Tupou VI Tupou VI ʻAhoʻeitu Tupou VI (Tongan: ‘Aho’eitu ʻUnuakiʻotonga Tukuʻaho; born 12 July 1959) is the King of Tonga. He is the younger brother and successor of the late King George Tupou V. He was officially confirmed by his brother on 27 September 2006 as the heir presumptive to the Throne of Tonga, as his brother (a bachelor) had no legitimate children. He served as Tonga's High Commissioner to Australia, and resided in Canberra until the death of King George Tupou V on 18 March 2012, when ʻAhoʻeitu ʻUnuakiʻotonga Tukuʻaho became King of Tonga, with the regnal name ʻAhoʻeitu Tupou VI.
Coronation of the British monarch since and including George IV, at least one year has passed between accession and coronation, with the exception of George VI, whose predecessor did not die but abdicated. The coronation date had already been set; planning simply continued with a new monarch. Since a period of time has often passed between accession and coronation, some monarchs were never crowned. Edward V and Lady Jane Grey were both deposed before they could be crowned, in 1483 and 1553, respectively. Edward VIII also went uncrowned, as he abdicated in 1936 before the end of the customary one-year period between accession and coronation.
