Piercing questions over UK carriers 26.04.12
5The Ministry of Defence's top civil servant is being called before MPs today to answer what are likely to be difficult questions about Britain's aircraft carriers.
Ursula Brennan has been summoned by the Public Accounts Committee to explain why there's been no official answer to a damning report about the multi-billion pound saga.
In October 2010 the Strategic Defence and Security Review changed Britain's carrier plans.
Both ships are still being built, but one is to be mothballed and the other converted to fly catapult launched planes - the F35-C Joint Strike Fighter.
Last year the public accounts committee claimed that the full cost implications of the U-turn were not properly understood.
Now the Permanent Under Secretary is being called before the committee to explain why the MOD is yet to answer that report.
Amid persistent rumours the Prime Minister may be about to go back to Plan A - finishing both ships and buying hovering planes - the F35-B - after all, her answers could be pretty telling.
