Sunny Hunday (on Twitter):  "Like Republicans, Tories face long-term demographic problems. Most UK population growth in south/SE & driven by minorities (Labour-leaning)".

This is why immigration needs to be brought down to zero, and the tax system used to encourage economic migrants to move on.

Otherwise, as Mr Hundal points out, the socialists are going to end up with an in-built majority that cannot be shifted (and please don't say we should try to win them over - we could only win them over by offering bigger bribes than the Labour party).
