Apparently Brexit, while a blow to globalism, can not fix the immigration problem by itself. It appears that the UK is trying to compensate the drop in EU immigration with an increase of Asian immigration.
Thus even if Britain exits the EU massive immigration from the Commonwealth can continue if that’s what the British Government wants.
It is also notable the massive failure of the “conservative” Theresa May government which is incapable of fulfilling its promise to decrease immigration to below 100 k per year.
Meanwhile “progressive” Britain is busy trying to increase the number of women and minority firefighters by dropping their test requirements below those of white men.
