Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what recent estimate the Government has made of the cost to the public purse to date of the adaptation of the Voyager aircraft for the transport of senior ministers.

To date the Departmental spend to convert one Voyager aircraft's cabin into an enhanced configuration is £8.9 million out of a total estimated cost of £9.6 million.

The aircraft's primary role will continue to be aircraft refuelling.
