asked the Minister of Aviation Supply what progress has been made in the multi-rôle combat aircraft development programme; and if he will make a statement.

As I stated in reply to a Question on 18th November, the first major phase of development is now under way on a tripartite basis.—[Vol. 806, c. 1217.]

Is my right hon. Friend aware that this collaborative V.G. Project is, both operationally and industrially, the core of our long-term aircraft programme and has the most major implications for the future of advanced technology in this country and must be persevered with virtually at all costs?

I would share my hon. Friend's view, but I would not always accept the term "at all costs".

What are the latest unit cost estimates from Panavia?

That must be the subject of another Question and I doubt whether we have the answer yet.

Have these aircraft sufficient range for widespread use in the Royal Air Force?

That is a matter for my hon. Friend the Minister of State for Defence.
