Protesters from Britain’s right and left took to the streets on Sunday, offering starkly different visions of the country’s future as the government scrambled to salvage its unpopular plan for exiting the European Union. The grievances that fuelled the Brexit vote are simmering once more. Disappointment may well inject new energy into the far right, said Professor Tim Bale. “The prospect that Brexit would fix everything was enough for all but the most rabid xenophobe. When people realize that it won’t stop the economy sucking in people to do the jobs that Brits can’t or won’t do, that it won’t stop people coming in via family reunification or asylum provisions, and that it won’t do anything to send home the millions of people here already, then there will be trouble,” Professor Bale said.
