A 56-year-old British grandmother has lost her appeal against a sentence of death by firing squad for trafficking drugs in Indonesia.

Britain's Foreign Office said it was "disappointed" after the sentence on Lindsay Sandiford was upheld by a Bali court. She has 14 days to appeal to the country's supreme court.

Sandiford, from Redcar in the north-east of England, was accused of being at the centre of a drug ring involving three other Britons. She insisted that she was set up and was forced by a gang to smuggle drugs to protect her children.

"We are disappointed to hear Lindsay Sandiford's appeal has been refused by the High Court in Bali," a spokesman for the British embassy in Jakarta said. "The UK strongly opposes the death penalty and has repeatedly made representations to the Indonesian government on this matter.
