The wedding was marked by a public holiday, AFP reports. The newlyweds reportedly waved to the cheering crowd as they left in an open-top car, and a reception was held later that night for some 4,000 guests near the royal palace.

A week-long series of wedding-related events will conclude Sunday with a royal luncheon in the capital, AFP added. The wedding came four months after the death of King George Tupou V in March.

Tupouto'a 'Ulukalala, 27, is first in line to the Tongan throne, the Telegraph reports, while his wife, 25, is 26th in line. (The Telegraph refers to Sinaitakala Tu'imatamoana 'i Fanakavakilangi Fakafanua as the prince's second cousin, while other reports simply refer to the couple as cousins.)

The BBC notes that marriage between cousins is seen as a way of keeping the royal bloodline strong in Tonga.
