The police are out of control. So is the government. We can only conjecture as to what possessed the senior officers who raided the homes and parliamentary office of Damian Green, the Conservative immigration spokesman. Yet their disdain for political process spoke eloquently to the authoritarian culture of our times.

In this respect, regardless of whether ministers played a direct role in Mr Green’s arrest, the blame rests squarely with the government. The police must be held to account for their heavy-handed intimidation, but ministers nurtured the climate in which such madness flourishes.
