Bali, Indonesia -

An Indonesian lawyer representing a convicted British grandmother has formally appealed the death sentence she received for smuggling cocaine worth $2.5 million into the resort island of Bali in a suitcase.

In an appeal filed to the higher court on Monday, attorney Fadillah Agus said Lindsay June Sandiford, 56, provided information that led to other convictions. However, that help was not considered by the court.

Agus said Sandiford acknowledged she committed the crime, but felt the sentence was too harsh.

London's High Court last month dismissed a case Sandiford filed against the British government, saying it didn't act unlawfully when it refused to fund her appeal.

Indonesia has very strict anti-drug laws and most of the more than 40 foreigners on its death row were convicted of drug charges. - Sapa-AP
