The Government has approved a treaty designed to deport the radical cleric Abu Qatada to Jordan to stand trial on terror charges.
The agreement, announced by the Home Secretary in April, aims to allay fears that evidence extracted through torture will be used against him.
The UK parliamentary scrutiny process completed at midnight, leaving a handful of legal steps before the deportation process can begin.
Home Secretary Theresa May has previously warned that future legal challenges could further delay the deportation.
Both houses of the Jordanian parliament and the country's king have also approved the treaty.
