Absolutely. My hon. Friend has made an excellent and salient point. He and I are both members of the all-party parliamentary group on shipbuilding and ship repair, which is currently undertaking a study of that issue. According to another study, conducted by the Fraser of Allander Institute at the university of Strathclyde, the overall benefit to the UK economy per annum from the shipbuilding industry on the Clyde alone is £366 million a year, in purely multiplier effects. As for the idea that we can competitively tender programmes overseas, we are losing the opportunity of industrial benefit as well. We are not just talking about the loss of core capabilities; we are talking about the loss of revenue and economic potential for our country.
