Jacinda Ardern, a former prime minister of New Zealand, has decamped to Australia. And think of all the Americans who have escaped from Donald Trump’s America. Ellen DeGeneres bought a massive house near Oxford. Ryan Gosling, fresh from saving the planet in “Project Hail Mary”, has set up shop in Hampstead.
