Veritas, Mrs Pritchard & The Purple Alliance

Did anyone remembering Veritas and watching the first episode of 'The Amazing Mrs Pritchard' feel a strange sense of deja vue as I did last evening?

Veritas proved that the British political set-up precludes entry of a new party, so it will be interesting to see how this far-fatched storyline develops over the next five weekly episodes!

What though is this link all about - The Purple Alliance??????????
