Former UBS rogue trader Kweku Adoboli is fighting against being deported to Ghana after an immigration tribunal decided he should be sent back to his home country.
Adoboli, who lost $2.3bn (£1.5bn) in unauthorised trading at UBS, was released from prison in June after serving out nearly half of the seven-year sentence he was given.
Home Office rules state that foreign nationals from outside the European Union sentenced to over a year in prison should be considered for deportation back to their home country.
Commenting on the tribunal's decision, Adoboli said it was "heartbreaking" and that he would appeal, with the offence having "nothing to do with his nationality".
Kweku Adoboli was arrested in 2011 and was found guilty on two counts of fraud in 2012.
During his hearing, Southwark Crown Court was told Adoboli was close to losing $12bn.
Adoboli had already been blocked from again working in finance as the Financial Conduct Authority (FCA) moved to ensure he cannot take a financial services position up again.
Having graduated from the University of Nottingham in 2003, he joined UBS as a graduate trainee, before becoming a trader in the global synthetic equities division, buying and selling exchange traded funds (ETFs) in 2006.
Adoboli's defence told the court that senior managers had knowledge of his actions and encouraged him to take risks.
