Good Guardian column by Matthew d’Ancona. I particularly like this:

The lesson of 2016 is that you are in a fight, and you lost the first round. This is not the moment for vague “One Nation” rhetoric. It’s a time of political combat – whether you like it or not. Resist kneejerk reaction, but don’t be afraid to take sides. Define your red lines and patrol them assiduously. This is the biggest political scrap since the cold war: autocracy versus democratic institutions; liberalism versus traditionalism; wall-building versus openness. The alt-right, Ukip and Breitbart understand that. Do you?

Spot on.
