If my prediction is correct, then the UK will be less than 50% white by 2030.
I'd say that's a bit of an overestimation, the University of Leeds has predicted that by 2051 ethnic minorities will make up 20% of the UK population.

Good luck UK, you were once a fine country
Still is a fine country if you ask me. I've got no problems with immigrants coming over as long as they come here to work (which a majority do).
