asked the Secretary of State for Defence whether the F111A will be able to carry British-made nuclear bombs.

Our primary requirement is for an aircraft to replace the Canberra as a tactical strike-reconnaissance aircraft carrying conventional weapons. But the F111A would also be able to carry the nuclear weapons the hon. Member mentions.

May I congratulate the right hon. Gentleman on maintaining the independent British nuclear deterrent, but could he give a categorical assurance that the bomb designed for the TSR2 can be carried in this new aircraft, if ordered?

I am always grateful when I get congratulations from the Front Bench opposite. I hope that it sets a precedent which others will follow. I can give the assurance for which the hon. Member for Cirencester and Tewkesbury (Mr. Ridley) asks.

May I ask my right hon. Friend what will be the cost of this plane, plus a nuclear weapon?

I would like notice of that question.
