Agreed wholeheartedly, but another tactic would be to move the battle from Brexit to the NHS. There’s nothing Britain cares about more, and the Tories are running the NHS into the ground prior, it’s suspected, to privatising large chunks of it. My guess is that’s not what 90+% of the electorate want. So attack the Tories as the anti-NHS party and switch them away from their Brexit theme. After all the NHS at the moment is neither strong nor stable.
