Introduce a hard border between all 4 UK countries. This is genius.
Thousands of new jobs created. Northern Ireland will be satisfied.

As for the Jocks we don't like them much and it will make them feel more independent.

The Welsh regard themselves as nothing to do with England already and with the severn toll abolished we are already conditioned to 50% of the inconvenience. Block all minor roads if necessary.
This is how they can deliver Brexit.

Another benefit is it will introduce more direct trade routes. GENIUS if I say so myself.

Where's the bloody tonic?
