Ian Dunt, writing at politics.co.uk:

What is happening is a tragedy. A betrayal of Britain’s role in the world. A betrayal of the Europeans who came and made this their home. A betrayal of the idea that this is a calm, sensible country, that thinks in practical and pragmatic terms about what it is doing, that deals in small ideas instead of grand ideologies.

The end of the dream. The start of the resistance.

Worth reading the whole thing.
