Clive Stafford Smith, Director of legal charity Reprieve, said:
This is a test for the Florida prosecutors - are they interested in exonerating Kris Maharaj, an innocent man in a wheelchair, or do they want to defend Pablo Escobar for two of the many homicides that he ordered.
It is also a test for the British Government - will they assist a British citizen to get the evidence he needs, or merely make statements about the need for fair trials?
- Krishna Maharaj spent 15 years on death row before his sentence was commuted to life imprisonment in 2002
- A judge will consider today whether files, believed to be held by US federal agencies, should be released
- The filing also sets out testimony provided by several other former members of Colombian drug cartels, who have admitted that Mr Maharaj was not involved in the murder
A Londoner who has been in a US prison in the United States since being sentenced to death in the late 1980s for a double murder is attempting to force the US government to hand over documents which could clear his name.
74-year-old self-made millionaire Krishna Maharaj was once the second biggest racehorse owner in the UK. He was convicted in 1987 of the murders of two men, Derrick and Duane Moo Young, in the Dupont Plaza hotel in central Miami.
