Brown calls for unity on terror
Gordon Brown has called for political parties to show "unity in the face of terror" in his first prime minister's questions session.
Mr Brown clashed with Tory leader David Cameron over the need for identity cards and a border police.
Pressed by Mr Cameron on whether he would ban extremist group Hizb ut Tahrir, Mr Brown said more "evidence" was needed before doing so.
A review on using phone tap evidence in court would go ahead, he added.
New Security Minister Lord West is to carry out an immediate review of the National Health Service in the wake of the attempted bomb attacks in London and Glasgow, Mr Brown said.
He also ruled out a call from Liberal Democrat leader Sir Menzies Campbell to set a date for the withdrawal of British troops from Iraq.
He said the UK had duties to the United Nations and the Iraqi government, adding: "We are not going to break those obligations at this stage."
