Concerns are growing for a missing Brighton woman after a scuba diving tour boat reportedly capsized off the coast of Thailand.

Millie Young, 57, from Brighton, and a female Thai crew member were still missing last night after the incident on Saturday morning.

The boat, which was believed to be part of a diving tour, capsized in rough seas.

Local media reports said the boat, called the Reggae Queen, got caught in the choppy waters around the Surin Islands archipelago in southern Thailand, a tourist hotspot for diving.

In a statement, a Foreign Office spokesperson said: "We are supporting the family of a British woman and are in contact with the local authorities after an incident in Thailand."

The search is continuing today.

The vessel had 18 people aboard and 16 of them have been rescued.

The Thai Navy, along with helicopters and the national coast guard, have joined the search for Ms Young and the crew member.

Ms Young, an artist, has been living in Thailand since 2007, according to a social media account linked to her.

The Foreign Office has been approached for further comment.
