Now if only we could get an acceptance that, similarly, the benefits of leaving do not have to be purely financial we might be getting somewhere

I have always fully accepted that but, to date, no one has given us a decent, valid study on what those benefits may be. Are you going to surprise us all and provide one now, Nigel?

As Keith points out, these were discussed at the time of the referendum (together with lies and exaggerations from both sides of the discussion)these are not complete, but they include:
Regaining control of our own borders. This allows us to control immigration. It is not xenophobic as it is not an attempt to stop all immigration.
Regaining control of our laws.
Regain control of our trading arrangements, allowing us to make trade deals with other countries without needing to add tariffs intended to protect the interests of French farmers (among others).
