Human rights campaigners expect Indonesia's Supreme Court to make a decision in Lindsay Sandiford's case "within 96 days" from her lodging an appeal today.
Zoe Bedford, from legal charity Reprieve, said:
Lindsay remains extremely grateful to the generosity of the public in raising the funds to allow her to file this appeal.
We are hopeful that the Supreme Court will take into consideration the compelling mitigating evidence in Lindsay's case and award her a sentence that is proportionate both to the offence and to her role in it.
In particular, it is hoped that the judges will give due consideration to Lindsay's cooperation with the authorities which led to the arrest and prosecution of more senior syndicate members, and take into account the need to encourage others to cooperate in the future.
The Government has done very little to support me. The Foreign Office (FCO) has done even less.
There are, and will continue to be, British nationals facing execution without lawyers and because they can not raise their voices the Government is standing by refusing to assist with funding of lawyers for them.
This action is tantamount to condoning the death penalty. Just giving and the public have done what the British Government fight not to do at great public expense.
The Government and FCO are doing all they can to resist me at this difficult time."
Action group Reprive said Lindsay Sandiford faces the death penalty because "she has no money to hire a lawyer for her appeal".
Never has there been a clearer example of how the death penalty falls predominantly on those who do not have the funds to defend themselves.
The FCO should step in to ensure she gets the legal support to which she is entitled - given it would cost them a fraction of what they spend on wine each year, it is hard to see why they are fighting against this in the courts.
UK High Court judges upheld the Government refusal to fund Lindsay Sandiford at the end of January, despite pleas that she was urgently in need of money and her family had exhausted all their available resources.
Despite prosecutors asking for a 15-year jail term, Sandiford was given the death sentence, after being accused of damaging the image of Bali The British Government said it was disappointed when she lost her bid to block the sentence.
Balinese police said Sandiford was at the centre of a drugs-importing ring involving three other Britons, but she claimed she was forced to transport the drugs to protect her children whose safety was at stake.
Today Sandiford's lawyers will go to the Court of Appeal today in London over a UK Government refusal to fund her appeal.
A Foreign Office minister said today that the Government remained "deeply concerned" about the fate of British grandmother Lindsay Sandiford, who faces the death penalty in Indonesia, but warned her legal bills would not be covered by the Government.
Hugo Swire said British diplomats had worked closely with Sandiford's legal team but speaking at Foreign Office questions in the Commons, he rejected a plea from her former MP Martin Horwood for financial aid.
Sandiford was sentenced to death by firing squad by a court in Bali for taking £1.6 million of cocaine on to the island.
Earlier this month Sandiford, originally from Redcar, lost the first appeal to the Bali High Court but is expected to take her case to Indonesia's Supreme Court.
We continue to be deeply concerned for both Lindsay Sandiford and Gareth Cashmore who have been sentenced to death for drug taking offences.
"We are seeking reassurances Indonesia will not seek to carry out the death penalty in both cases."
– Hugo Swire, Foreign Office
"I thank the Foreign Office for the support they have given to my former constituent Lindsay Sandiford.
"But given the concerns about the adequacy of translation in the initial trial and the adequacy of legal representation going forward to the Supreme Court stage, will the Foreign Office re-consider its position and follow Indonesia's own example which provides support for translation costs and legal costs for its nationals facing the death penalty abroad?
"Will it actually support Lindsay Sandiford through that process even though it is not legally obliged to do so?"
– Martin Horwood, MP for Cheltenham
"You are right to raise the concern but it is true to say the Government does not pay for legal representation for British nationals overseas.
"We have been working extremely closely with Lindsay Sandiford's lawyers and in identifying a lawyer for her.
"We are prepared to assist her with anything beyond actually having to meet some of these bills, which we just simply don't do."
