Crown Prince of Tonga Tupoutoʻa ʻUlukalala became heir apparent to the throne in March 2012 upon the accession of his father, Tupou VI, as King of Tonga. He was subsequently bestowed with the noble title of Tupoutoʻa. He was retained as foreign minister in the cabinet of Prime Minister Fatafehi Fakafānua when he took office in December.

Marriage

On 12 July 2012, Crown Prince Tupoutoʻa ʻUlukalala married his double second cousin, Sinaitakala Fakafanua, in a wedding attended by 2,000 people. He was 26 years old at the time, while his wife was 25 years old. Tongan royal protocol requires that members of the royal family only marry members of noble families to maintain a 'strong' bloodline.

A maternal uncle of the Crown Prince, Lord Vaea, defended the marriage saying, "It's a new beginning for the royal household. They are both in their twenties, we are looking at that to preserve that constitutional monarchy within Tonga."
