Guardian editor-in-chief Alan Rusbridger has told ITV News the detention of the partner of one of his journalists at Heathrow Airport was something out of an "Alice in Wonderland world".
He said holding David Miranda at the London airport for nine hours without a lawyer was a "misuse of a terror law to inhibit journalism".
Mr Rusbridger also said being ordered by a senior Whitehall official to destroy material that the newspaper already had copies of in Brazil and America was "one of the more bizarre days in Guardian history".
He claimed security officials were worried about Chinese and Russian agents "surrounding" the Guardian's London headquarters.
The independent reviewer of terrorism legislation said he will examine the detention of David Miranda at Heathrow Airport.
Nick Clegg has backed David Cameron's decision to send a top civil servant to The Guardian to urge them to destroy classified data.
The Guardian journalist whose partner was held at Heathrow Airport hits out at the UK as he gives ITV News his first British TV interview.
