Set to be put on a flight back to his native Ghana on Tuesday, former UBS rogue trader Kweku Adoboli is mounting a last-ditch effort to stay in Britain.

Kweku Adoboli is fighting his imminent deportation to Ghana, where he last lived when he was four. Adoboli, who served more than three years in prison for a $2.3 billion rogue trading scheme which surfaced in 2011, is asking for a last-minute judicial review, according to British newspaper «The Guardian».

It is Adoboli's last chance: the 38-year-old has been held in detention near to Heathrow pending his removal from the U.K. on Tuesday. Since his release from prison three years ago, he has spoken out on the culture in investment banking. He never took British citizenship, a decision Adoboli says he now bitterly regrets. He has resided in Britain for the past 26 years and currently lives with friends, for whom he is partly responsible for childcare.

The former banker and son of a former Ghana diplomat, Adoboli is not permitted to work in Britain. His deportation was fought by 114 members of British parliament. A crowdfunding campaign to help defray his legal costs raised nearly £20,000 ($26,050) in several weeks.
