Having just checked The Electoral Calculus prediction for Peterborough, they put Labour with the highest chance, then Tory, with LibDem and Brexit party in the doldrums. I think that is wrong - Farage will certainly be doing his damnedest to get the Brexit party as high as possible, and the more he succeeds in that, the stronger the anti-Brexit response will be, which will primarily help the LibDems. And neither Labour nor Conservatives are being too convincing at the moment.

We will just have to wait and see how it plays out.
