We are an island

So they want to control / eradicate and generally keep Coronavirus at bay?

No they don't. What they want to do is have life as per normal and attempt to prevent it from taking hold in the UK.

News for your Boris. We are an island.

If the worst comes to the worst we should close the channel tunnel, stop all incoming flights and shipping and isolate ourselves. There will be problems with trade, food imports and much, much more so my solution is pretty half-baked: but it could be a solution.

Many years ago my father told me that what saved us in WW2 was the English Channel. Having built the tunnel all sorts of things can get through but, so far, rabies has not.
