It is not self-evidently ridiculous that Nigel Farage should be the next British ambassador to the United States. The wishes of the president-elect should not automatically be discounted. John F. Kennedy’s wish that his friend David Ormsby-Gore (Lord Harlech) should be ambassador was granted. It is also not true that the post must be filled by a professional, or that the Prime Minister should not appoint a political rival to the post.
