The partner of a journalist who was detained under terror laws at Heathrow for nine hours has said that he was questioned about his "whole life".

David Miranda was speaking after he arrived in Rio de Janeiro, where he lives with Guardian reporter Glenn Greenwald.

Mr Greenwald has in the past published documents leaked by US whistleblower Edward Snowden.

Police have not said why Mr Miranda was held, but he said he was kept in a room and quizzed by "six agents".
