A difficult path is likely ahead for the UK, but the change should allow them to more easily align their fiscal policy with their monetary policy.
This event is also a good opportunity to distinguish “triggers” from “causes”, because a trigger can often be mistaken as the cause.

When the cause allows significant strain, any number of various trigger events can create disruptions.
