Babar Ahmad, a British citizen, is due to appear in court in the final stage of his battle to avoid extradition to the US.
The US government claimed Ahmad was affiliated to websites promoting terrorism, which led to him being held in prison for eight years without any charge.
Ahmad has repeatedly denied the claims against him, and has taken his fight against extradition to the European Court of Human Rights.
