The British embassy in Nuku’alofa has reopened, nearly 13 years after it was closed.
Mr Robin Ord-Smith MVO has been appointed High Commissioner to the Kingdom of Tonga, a statement said.
He will succeed the current, non-resident High Commissioner, Ms Melanie Hopkins, who will remain High Commissioner to the Republic of Fiji.
Mr Ord-Smith will take up his appointment during summer 2019.
The British consulate was closed in Tonga in 2006.
Tonga’s diplomatic relationship with Britain could be traced back to 1880 after the Treaty of Friendship between Great Britain and Tonga was signed in 1879.
