The Foreign Office is seeking confirmation that a British grandmother has lost her appeal against a death sentence for trafficking drugs into the resort island of Bali.
There are unconfirmed reports that a three-judge panel at the Supreme Court in Jakarta unanimously rejected Lindsay Sandiford's appeal.
They have agreed with the decision taken by Bali's Denpasar district court, which sentenced her to death, and the island's high court, which rejected her first appeal.
Sandiford, 56, from Cheltenham in Gloucestershire, was sentenced to death by firing squad after being found with cocaine worth an estimated £1.6 million as she arrived on the Indonesian island on a flight from Bangkok, Thailand, in May last year.
A Foreign and Commonwealth Office spokesman said: "We are aware of unconfirmed reports that the decision of the Indonesian Supreme Court has been announced. We are seeking confirmation of the decision from the Indonesian Supreme Court.
"We will continue to provide consular assistance to Lindsay Sandiford and her family at this difficult time."
She was sentenced in January.
Balinese police claim Sandiford was at the centre of a drugs-importing ring involving three other Britons. She denies the allegations, claiming she was forced to transport the drugs to protect her children, whose safety was at stake.
Sandiford, originally from Redcar, Teesside, was arrested at Bali's airport after 10.6lb (4.8kg) of cocaine was found in the lining of her suitcase during a routine customs check.
She was later accused of damaging the image of Bali and received the death sentence following her trial. The penalty was imposed despite prosecutors asking only for a 15-year jail term.
