Bill Shaw's family demand his release from Afghani jail
The Kent family of a British man jailed in Afghanistan have handed a petition into Number 10 calling for his release.
Ex-Army officer Bill Shaw, 52, from Leeds, West Yorkshire, was tried in April on corruption charges.
His family and supporters maintain his innocence and are calling on the British government to intervene.
Mr Shaw, who served 28 years in the British Army and was awarded the MBE, was working for security firm G4S.
He admitted paying £13,000 for the release of two impounded vehicles in October but said he believed he was paying a legitimate fine.
His daughter, Lisa Luckyn-Malone, from Dover, Kent, handed in a 5,000-strong petition ahead of her father's appeal hearing in Kabul on Saturday.
She was joined by Mr Shaw's wife, Liz, his grandchildren Madeleine and Caius, and Dover MP Charlie Elphicke.
After visiting her father in Pul-e-Charkhi prison in Kabul earlier this month, Ms Luckyn-Malone said he was "truly shaken, physically weak and genuinely scared".
"To see my father struggling and in danger is totally unacceptable," she said.
"During his long and exemplary military career, he put his life at risk for Queen and country.
"This should not be happening to such a distinguished and honourable man who has always lived his life by the highest standards of honesty and decency."
