My right hon. Friend makes a really good suggestion, and I will take it up at the NATO Defence Ministers’ meeting for him. He is right. We already have a number of international coalitions in the strait, such as on anti-piracy, which even involves China, and the International Maritime Security Construct, where we are working with the Americans on protecting our tankers. He is right; tanker wars, as they were called in the 1980s, have been around for a long time. The Iranians used to fire rocket-propelled grenades at tankers back then, deliberately to spike the oil price. He makes a good suggestion.
