Brexit is here. Most of Britain shrugs.

When the sun rises over Britain on Saturday, the country will no longer be part of the European Union.

The issue of whether to stay or leave has already divided British families, cast a shadow over businesses and paralyzed the government, writes our London bureau chief, Mark Landler. And the trade talks that Prime Minister Boris Johnson’s government will have with the bloc’s leaders in the coming months could prove just as traumatic.

But for now, Mark writes, the prevailing emotion in the United Kingdom is a characteristically British reflex: Get on with it.

Another angle: Pro-Europe “remainers” are girding for new battles over how Brexit will affect trade and immigration, among other issues. Some of them see the American left’s response to President Trump’s 2016 election victory as a useful model.
