I happen to agree with Brydo that candidate selection in these vacated seats will show a distinct move to the right. After all, most of the candidates not standing are centrists or those that have had the whip removed for disagreeing with distinctly right wing led policy. It makes sense to assume that the PM wants to strengthen the far right of his government benches in the next election. The same goes (only left) for the few vacated Labour seats.
I also believe that Labour is controlled by the extreme left of the party. Seumas Milne and Momentum have an iron grip on Jeremy Corbyn to the point that they are totally unelectable at this moment in time (in my opinion)
The Lib Dems and the Brexit party have both taken opposite ends of the Brexit argument, but have made sure they remain “minority parties” as they they will both stand on a “Single Issue manifesto” and will convince no one that they have an agenda for running the country on a day to day basis. They will no doubt have an influence on the way individual constituencies end up being represented, but that’s as far as they can go (again in my opinion).
My view is that the conservatives will win the next GE, but I wouldn’t like to predict whether they will gain a workable majority (if I were to guess I think it unlikely).
Perhaps it’s time for the creation of a new “Centre Party” formed by an amalgamation of the reasonable minded decent politicians on both sides whose function has been taken away from then by two groups of zealots. One thing’s for sure, we cannot hope to improve the UK while Parliament remains in the grip of two parties controlled by polar opposite extremes.
This is only my own personal view of things folks.
