The rise of isolationism in the Conservative Party

A FEW YEARS ago Britain liked to think of itself as the belle of the globalisation ball. David Cameron invited Xi Jinping, China’s president, for a state visit that involved a trip down the Mall in a gilded carriage and a banquet in Buckingham Palace. He wooed Angela Merkel, Germany’s chancellor, in a bid to breathe new life into Britain’s membership of the European Union. He liked to boast that his friendship with Barack Obama, America’s president, was so close that Mr Obama had once tucked him up in the presidential bed on Air Force One.

Boris Johnson came to power promising, in a very Johnsonian manner, to preserve Britain’s pro-global stance while also delivering Brexit. He routinely referred to the Europeans as “our neighbours and partners”. He got on famously with Donald Trump. Shortly before taking over as prime minister he told a Chinese TV station that his government would be “very pro-China”. He repeatedly insisted that there are two possible versions of Brexit: Nigel Farage represented the inward-looking and xenophobic one while he represented the outward-looking and cosmopolitan one.
