Well the country is already considerably right-wing and as the country buckles under the pressure of maintaining the current system it can only push that discontent further to the right, this time round Conservatives made an alliance with Farage/BXP that funneled that discontent into what we see now as "One Nation Tory" in the future it'll be even more of "Whites are becoming a minority, vote for Britain to keep it true".

Being hopeful, eventually the boomer lot are dead and there are enough millennial to push it back the other way but to be honest as a non-white millennial I think the damage will be done by then (economically and environmentally). Literally right now I'm sat in an office with the type of guy who thinks that any advancement of people of colour is somehow "insanity" and an attack on "his" ideals.
