Rodders - I’ll put this here to save time as you try and sort PMs.
First thing - if you haven’t yet done it please call the Foreign Office
tonight on 020 7008 1500.
It’s a 24/7 manned line. It’s there to help Brits whose relatives are/were overseas. They will want as much info as you can give them on Roy (full name, date of birth, last known address in Thailand etc etc). They will then enter this info on a database which will be accessed first thing in the morning by the embassy in Bangkok, who will then take action.
Contacting the FCO tonight will mean this gets looked at first off, Monday morning. If you leave it there’s a risk nothing will get done until Tuesday, given the time difference between here and Thailand (6 hours).
Getting it into the FCO system will also mean you’ll get appointed a London-based point of contact who you’ll be able to speak directly to going forward. They will be able to advise you on Thai procedures, repatriation, etc etc and act as a liaison between you and the Embassy in Bangkok. There’s no point contacting the Embassy direct as they will refer you back to the London office, given that you are in the UK. Sadly, they handle a huge number of this kind of case every year so know what they are talking about, and are fully trained.
After you’ve contacted the FCO I would ask that you read their guide on initial steps to take for a Death Abroad. You can access this at
https://www.gov.uk/government/publications/coping-with-death-abroad/death-abroad-initial-steps
This will give you a quick idea of what will unfold over the following days, and how the FCO/Embassy can help you - and where their remit doesn’t run to.
I hope this helps for now. If you have other questions, pls ping them via a PM.
Again, sorry for your loss. I hope the messages of fond remembrance of Roy from his old mates here give you some comfort at this very sad time.
