Britain could remain tied to the European Convention on Human Rights (ECHR) until 2022 - despite Brexit.
The news comes as senior Government officials suggest a plan to leave the ECHR won't be on the Conservative manifesto for the upcoming election. They claim it will represent a distraction for the Government as it tries to negotiate a Brexit deal.
Eurosceptics have always claimed the ECHR gives the European Court of Human Rights too much influence over UK law.
Iain Duncan Smith, MP for Chingford and a key Brexiteer, called the potential omission from the manifesto a necessary measure, despite his disappointment.
The decision to leave the ECHR was blasted by numerous political figures, including former Scottish First Minister Alex Salmond.
