By banging on about immigration, Cameron risks making it central to the question of whether Britain should remain in the EU. He is, after all, the politician who has promised to hold a referendum in 2017, if he is still Prime Minister, on whether to stay or leave, following a period variously described as a “renegotiation” of the UK’s membership and “reform” of the EU’s structure.
转换话题也有利于国家利益。强调移民问题的卡梅伦有可能让英国是否应该留在欧盟成为问题的核心。毕竟，是他承诺如果2017年仍在位就将举行是否留在欧盟的公投，在此期间则是被频繁描述为英国成员地位“再谈判”和欧盟结构“改革”的时期。如今，他似乎正在把移民问题打造为这一努力方向的关键考验。
