Healthy opposition is not a sideshow, without it, democracy is a sham. An unelected but actual opposition, is much better than two ideologically similar parties passing the baton back and forth.
We here in Ireland have a two party system where there is no visible ideological difference between the parties and it's been utterly disastrous. We have an actual opposition in the parliament now and it's arguable whether it's having a positive effect (I think it is) but the conversations are at least being had and people are being held to account.
Again. Perfectly understandable, were that to be the case.
However, we can all see what damage the last election has done. Giving Boris and the Tories an 80 seat majority; leaving them to do whatever they choose.
That must never happen again. And that is precisely why Labour has got to become electable. Which means listening to the public and not telling the public what it should want as an ideology.
