Some very good and important points in this, especially in the last two paragraphs:
You could say that in elected dictatorships, the state purges the civil service and judiciary and controls the media and Britain has not reached that point. But instead of looking at the terminus, notice the direction of travel. Johnson has suspended parliament and purged his party of dissenting pro-European voices. Attacks on the independence of the judiciary and civil service are now standard for a right that cannot tolerate constraints.
Britain is not Hungary. But if you want to stop your country heading that way, is it not more effective to start fighting back at the first sign of danger rather than waiting until it is too late?
