You vastly overestimate the contents and capabilities of the central intelegence agency.   Socialsim fails Even when it is tried in America , for the same reasons and in the same ways it fails everywhere else.

If you got your Corbin British indistry would be fleeing the united kingdom as fast as they can your economy would start to decline rapiitly those that remain would be betting that his government would collapse.

You would probably be diluted enough as to blame brexit for the Corbin desasterus decline but brexits raising of tarrifs to a mere 2.5% like the rest of the world pays in a hard brexit can't even come close to what Corbin would have to do to the economy to pay for all his new votes.
The UK lost big, and it's fixing to lose a lot bigger in the decades to come. Soon enough the demographic majorty in the UK will be those who treat non-musums like 2nd class citizens and women even worse.  So to be honest your policies don't matter long term.
