Abdel Basset al-Megrahi, the man convicted of the Lockerbie bombing, has revealed fresh evidence which he believes proves his innocence and which attacks the credibility of the Maltese witness in the case, Sky News has reported.
Sky said that on a website set up to give details of the appeal he eventually dropped, Megrahi attacked the credibility of Tony Gauci is the Maltese shopkeeper who said Megrahi bought clothes in his shop that were subsequently found wrapped around the Lockerbie bomb, and whose evidence subsequently convicted the Libyan.
The Libyan and his lawyers are now saying the shopkeeper's evidence was inconsistent and important details were improperly kept secret.
They said they included information that could have been used to undermine the shopkeeper's credibility in court, such as:
* That just before picking out Megrahi in an ID parade, the shopkeeper had seen a press photo of the Libyan. The defence team did not know the shopkeeper had also compared Megrahi's photo with one of convicted terrorist Abu Talb, who they think was the real bomber.
* That there were inconsistencies surrounding the date the clothes were bought. The shopkeeper said it was before the Christmas lights were put up in his home town.But a local MP who performed the switching on ceremony said he had flicked the switch the day before the purchase. Also, at one stage Mr Gauci told Crown prosecutors that the date of purchase was actually November 29, a fortnight before Megrahi was said to have bought the clothes.
* That there was a new and potentially crucial independent witness who could have cleared Megrahi. It was someone who claimed to have been in the Maltese shop when similar clothing to that around the bomb was being bought. The purchase was made by two Libyans, neither of whom were Megrahi.
* That the Maltese shopkeeper and his brother were given substantial rewards from the US Department of Justice following the Lockerbie trial. Megrahi's lawyers say that had they known about the lure of a cash reward, they could have cast doubt on Tony Gauci's credibility as a witness.
And then there were the secret papers.
Confidential documents - which could relate to international intelligence - remained a mystery because British Foreign Secretary David Milliband did not want them revealed in court.
He said secrecy was in the public interest. But Megrahi's lawyers say it denied him his right to a proper appeal.
Megrahi is the only man convicted of the 1988 Lockerbie bombing which claimed the lives of 270 people when a Pan Am jet was blown out of the sky.
The Libyan was controversially released in August from his life sentence on compassionate grounds after being diagnosed with terminal prostate cancer.
