Will the Prime Minister join me in welcoming the launch today of Environmentalists for Europe, which is co-chaired by Stanley Johnson, the father of Boris Johnson? Will he also welcome the splendid article last week setting out the importance for science and technology of remaining in the European Union, which was penned by his Minister for Universities and Science, who is the brother of the hon. Member for Uxbridge and South Ruislip? Will he have a word with his hon. Friend to tell him about the importance of family solidarity and of joining the swelling ranks of Johnsons for Europe?
