The Brexit referendum decision has thrown Britain into its most profound crisis of modern times. Where now are the three circles which defined the United Kingdom’s position in the world – the special relationship with the USA, leadership of the Commonwealth, and membership of the European Union?

Whatever the outcome of Brexit, Britain will have to develop one new narrative from the three mainly fictitious circles of the past. Three Circles into One is a clear-eyed analysis of a national self-inflicted catastrophe and essential reading for all those trying to understand the mess, how it came about, where it might lead, and how to steer a future path.
