Strategic Defence and Security Review

My right hon. Friend is absolutely right, and I am grateful to him for that point. He mentioned the firms in his patch in Rotherham. It is indeed striking that in the supply chain for the Astute submarine programme alone, which is a significant but relatively small part of the overall defence industry in the United Kingdom, there are, by my reckoning, more than 1,400 firms, spread over 1,500 areas of the country, that contribute in some way—either directly, because they are defence contractors or small or medium-sized enterprises, or indirectly, in that although they not part of the defence industry, they none the less get important business from the Astute programme.
