John Bercow Fronts The Move To Relocate PM Complex From The Chamber.

John Bercow, Chairperson

Following the security challenges that the parliament complex has being facing from terrorist attacks, the house agreed to build another complex to battle the insecurity tread that is facing the members while seating says John Bercow.

According to minutes of a commission meeting chaired by Speaker John Bercow last month, the cross-party committee 'endorsed the principle of the construction of a contingency parliamentary chamber on the Northern Estate subject to further investigation of time and cost'.

The project is now envisaged as a 'legacy' of the Northern Estate refurbishment.

The second chamber could also end up being used if the multi-billion pound restoration of the palace goes ahead, with the traditional green benches expected to be out of action potentially for years.

The Restoration & Renewal proposals estimated the cost of building a temporary chamber in Richmond House at £85million.

Labour MP Chris Bryant, who headed up a cross-party committee on the refurbishment project, insisted earlier this year that a temporary chamber would be 'properly impressive' rather than 'some cardboard cut-out'.

A Commission spokeswoman said: 'The House of Commons' main priority is to ensure that the business of government, legislation and scrutiny - particularly in the Chamber - is continued in the event of any disruption.

'It is good business practice for any organization to have such arrangements in place.'

Tory MP Shailesh Vara, who has been fighting against plans to shift MPs out of parliament while the restoration scheme is carried out, told MailOnline: 'I am very concerned as are many other MPs about decisions costing huge sums of taxpayers' money being taken without proper consultation of parliament.

'Given the recent debates on this subject there is a clear understanding that decisions on alternative chambers, decanting and the like will be taken by parliament, and not one of its committees.
