A Briton sentenced by a French court to a 22-year jail term for drug-trafficking is seeking to have his conviction overturned on the grounds police allegedly used forged documents, according to his complaint seen by AFP Wednesday. Robert Dawes, 48, who had denied the charges, was arrested at his luxury villa on the Spanish Costa del Sol in 2015 following a lengthy investigation by the authorities in Britain, France, Spain and South America. Spanish police secured a video showing him bragging to a member of a Colombian drugs cartel about his ownership of cocaine found stuffed in 30 suitcases registered to ghost travellers. The drugs were said to have a street value of 50 million euros. Dawes on Friday filed a complaint seen by AFP in which he accuses police officers of giving false evidence on the methods the anti-drugs task force used to seize the 1.3 tons of cocaine at Roissy Charles de Gaulle airport. According to Dawes' lawyers, the elements of the initial police report of the drugs seizure do not match an officer's later declarations. France's highest court is due to examine Dawes' appeal on April 14. gd/ech/sjw/jj
