No country did more than Britain to establish the values of free speech and equal justice under the law. In 1215, King John issued the Magna Carta, which established that even the king was subject to equal justice under the law, and in 1644, John Milton published his famous defense of free speech.

That tradition is now at grave risk of being destroyed, says UK journalist and professor Matt Goodwin. He says that the arrest by six police officers of a father who complained on WhatsApp about the local school “is merely the latest symbol of a much broader assault on free speech and free expression.”

And it comes at a time when the government’s Sentencing Council is recommending that judges give preference to non-white criminal defendants, undermining the principle of equal justice under the law.
