Wealth inequality in the UK has been going up since the 1970s.

This is a trend, however, that is generally occurring in pretty much every first world country and isn't unique to the UK

Nor the lib dem nor honestly labour policies are radical enough in dealing with climate change. Corbyn obviously won't stop climate change, I personally think he should be a lot more vocal about it. Nonetheless, the reintroduction of left-wing policies into mainstream view will give the issue more publicity and (in my view) help shift the public's perspective to one where climate change is the no.1 issue. Naturally, there are other factors that have to come into play for this to occur I admit.
