The Supreme Court has said Lindsay Sandiford, the grandmother on death row in Bali, "remains in jeopardy" and is in "urgent need of legal help".
The 57-year-old from Cheltenham has lost a battle at the UK's highest court over the lawfulness of a Government policy not to provide funding for legal representation to Britons facing capital charges abroad.
Five Supreme Court justices in London unanimously dismissed a challenge by Sandiford, who was convicted last year of trafficking drugs into Bali and sentenced to death by firing squad.
The Supreme Court called on the Government to carry out an urgent review of whether funding for legal representation can be given in the case.
Grandmother Lindsay Sandiford, who is on death row in Indonesia for trafficking drugs to Bali, has lost her latest battle at the UK's highest court to get funding to fight her case.
Sandiford, 57, from Cheltenham, Gloucester, was sentenced to death by firing squad after being arrested in May 2012 for smuggling 4.8kg (10.6lb) of cocaine worth £1.6 million from Bangkok.
She claimed she was forced to transport the drugs to protect her children, whose safety was at stake.
An appeal against her sentence was rejected but she is continuing to fight her case.
However, she is currently without legal representation and tried to challenge the lawfulness of a Government policy not to provide funding for Britons facing capital charges abroad.
But today five judges in the Supreme Court unanimously dismissed her case ruling the policy was lawful even in death penalty cases.
A Colombian shaman is showing no remorse and taking no responsibility for the death of a teenager from Bristol who drank a hallucinogen during a tribal ritual. The body of Henry Miller, 19, was found last week after he and other foreigners attended a ceremony led by shaman Guillermo Mavisoy.
Mr Mavisoy said it was common to vomit and become ill while consuming the concoction called yage. But he said he had never seen anyone die during the decades he has been serving the herbal concoction made from the namesake vine and other plants native to the Amazon rainforest.
Henry Miller's body was found last week dumped near Mr Mavisoy's modest home after he and other foreigners attended a ceremony led by the shaman. The authorities have yet to determine the cause of death but say the 19-year-old fell ill during the ritual

"When it's time to die, you die. You can take the safest pill in the world and you can die. It doesn't matter if you have lots of money when the time has come."
The body of a teenager from Bristol who died after drinking a hallucinogen during a tribal ritual was left by the side of the road by two frightened local men, according to Colombian authorities.
Henry Miller, who was 19, was in a remote rainforest area of Colombia with other tourists.
Mr Miller, who was due to go to university in September, is understood to have taken Yage which brings on vivid hallucinations and supposedly spiritual experiences.
He was found dead on Wednesday by a rural road outside Mocoa, the capital of the Putumayo region.
Mr Miller's health deteriorated after drinking the brew and the shaman sent him to a hospital on a motorcycle with two local men, but he died en route, Putumayo police commander Ricardo Suarez said.
The cause of death is not determined and no one has been arrested.
