PFR,
Keith - still waiting for a recomendation for the centre party you will vote for,

Tricky, and Brexit which is neither Left, Right or Centre is an over-riding issue now anyway.

I can only say what I have done. I voted Labour when it was on the Centre ground, but they moved away.
The Tory leadership now is still much closer to the Centre than the Labour leadership, though much of Labour's PLP remains at the Centre.

If Momentum and Corbyn fall, I will be voting Labour again.
If, as seems likely, the Tory leadership changes and moves further Right I will have a real problem.
Then there is Brexit!
