Does my hon. Friend agree that it is not just a question of defending the United Kingdom’s territorial waters and our contribution to NATO, but goes much further afield? We forget that the maintenance of a blue-water Navy is vital to trade. One only has to look at the Red sea. I used to ship coffee from the Port of Tanga through the Suez canal to Europe and around the world. Piracy around the Red sea was rife; ships were hijacked until the European Union force and others, led until recently by the United Kingdom, were there with ships built in Scotland.
