Around the world, coups are normally international events. Short of war they have been a preferred mechanism to achieve what has become known as ‘regime change’. And the last time there was a successful coup in this country in 1688 that too was an international affair, with Mary and William of Orange being installed as a monarchy. That was a coup by parliament against an over-bearing monarchy.
The current situation is quite different. We are living through a coup against parliament by a minority of parliamentarians, who have seized control of the Tory party from the right. They intend to impose their will against the majority of elected representatives and against the will of the public.
They are able to attempt this because this too is an international affair. Boris Johnson hopes to prolong his premiership by crashing this country out of the EU with a No Deal Brexit. But the key beneficiary of this project is Donald Trump and the interests he represents, and the project has his full backing.
