A Conservative former minister has accused the Government of approving the detention of David Miranda, suggesting it had allowed police to "misuse" anti-terror laws.
David Davis said the Home Office, Foreign Secretary and "almost certainly the Prime Minister" would have been aware of the move to hold and question Miranda.
"No one's suggesting they directed it, but they approved it by implication," said Davis, who was Foreign Office Minister under John Major.
"If the Home Secretary is told this is going to happen and she does not intervene, then she's approving it," the MP added.
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.
