My brother is very ill in a hospital in Bangkok, Thailand. Arrangements are being made for his medical repatriation to Britain. He will need medical supervision on the flight from Bangkok to Heathrow Airport and then in an ambulance from Heathrow to a suitable hospital. I have been told that £1000 is needed to pay for a private ambulance to take him from the airport to a suitable hospital. For some reason, the NHS will not do this. Please help my brother.

Thank you.
