Three Britons convicted on drugs charges in Dubai, who claimed they were tortured in prison, have been freed in an amnesty, diplomatic sources in London said Friday.

Grant Cameron, 25, Karl Williams, 26, and Suneet Jeerth, 25, all from east London, were convicted in April of possessing for consumption more than one kilogramme (2.2 pounds) of synthetic cannabis known as Spice.

They were jailed for four years each and the Dubai Appeal Court upheld their sentences.

A Foreign Office spokesman said: "We are aware that the 2013 amnesty list has been announced in the United Arab Emirates and that the local authorities have begun the process of releasing those included.

"This will continue to come as welcome news for those included and their families.

"It would not be appropriate to discuss details of specific cases. Questions about next steps are best answered by the UAE authorities. We will continue to provide appropriate consular assistance.

"We understand that if there is deportation involved, British nationals will be deported back to the UK."
