Peter Hain has called for the creation of a Westminster security chief after a newspaper managed to smuggle a fake bomb into parliament.

Friday's papers continue to analyse the ramifications of Wednesday's House of Commons security breach.

The Sun adds to the controversy by having a reporter smuggle a fake bomb into parliament less than 24 hours after the Commons invasion.

The journalist had been working as a waiter for the past three weeks and managed to get the job after his bogus references weren't checked.

Commons leader Peter Hain, who has called for a new director of security to be appointed, said this latest breach "confirms all my worst fears".

He added: "Frankly, the Sun has done the House a favour by exposing the amateurish and old-fashioned culture which is a threat to the very cockpit of our democracy."

On Thursday Metropolitan Police commissioner Sir John Stevens said Wednesday's invasion of the Commons was likely to have been an "inside job", aided by an MP or member of staff.

He added that claims of police misconduct against hunt protestors were unfounded.

"No-one got cracked over the head for no reason," he said.

Meanwhile, the Times claims that the option of a head of security was rejected late last week by the joint committee on security, a body of senior MPs and peers from all parties, which advises the speaker and chairman of the House committee in the Lords.

The committee felt that a "unicameral" director would not work because of the separate nature of the Lords and Commons.
