Books on Brexit explaining how and why parts of Britain voted to leave the European Union are falling hot off the press. Some promise the full story of the political manoeuvring that got us to this point, others promise to make sense of the vote, with a couple focusing on the supposed evils of immigration and Islam. In Rule Britainnia,  Danny Dorling and Sally Tomlinson tell a different story. They argue that the EU referendum was part of a last gasp of empire working its way out of the British psyche. It is a view of empire largely based on myth and nostalgia. Dorling and Tomlinson are not arguing for any particular position, but suggest that whatever the next year brings Britain will be much diminished by the process of trying to leave the EU, and that there is no welcoming Empire, Commonwealth, or other set of countries, ready to quickly embrace new trading relationships with us. They do, however, recognise the potential to reshape a post-Brexit Britain, assuming that the UK can accept a world order not based on the past.
