An asylum seekers' centre could only be closed if a catastrophic event happened once it had been given permission to open, an inquiry heard.

Surplus Ministry of Defence land between Piddington and Blackthorn, near Bicester, is one of two sites chosen by the Government to test a 750-person asylum seekers' centre. The other site is at RAF Newton, in Nottinghamshire.

During the second day of the public inquiry, Peter Wrench, director at the Immigration and Nationality Directorate, said that as there would be a substantial investment, it would not be closed unless there was a catastrophic event.

Mr Wrench said: "There would have to be an effective return on the Government's investment."

Mr Wrench said although the Home Office was still actively looking at other sites, it did not have a contingency plan to replace the Bicester site.

In cross examination David Elvin QC, for Cherwell District Council, accused the Government of not looking at enough sites.

He said: "Greater care should be taken looking at alternative sites rather than restricting themselves like it has done."

He argued the size and location would have an impact on the well-being of residents, and local people.

Afterwards David Hughes, Arncott's district councillor, said the Government should have chosen a site with a better chance of success.

He said: "The Government should be thinking of the interests of local people as well as residents in these centres."

The inquiry, which is being held at Bicester Garrison Theatre, Graven Hill, near Bicester, continues on December 12.
