How stupid and pointless to say that immigration is below population increase.
Unless it is the only factor, OF COURSE IT IS!

Look at this month's population graph from ONS. http://www.statistics.gov.uk/pdfdir/pproj1009.pdf
Figure 4 shows the highest and lowest future population rise for various factors. On the minimal reasonable assumption for immigration based on the best and most up to date figures, it is shooting up.

Who else apart from you thinks that is OK?
Our 3 main parties agree on little, but they agree immigration is too high. Most of the population do too. It seems everyone does except you. I have asked several times if you know of one credible individual who agrees with you.
Silence.
You have a mental block on this and it is pointless arguing with you.

Re controls, the numbers entering across beaches is minute and negligible. Immigrants come in through air and sea ports.
We should invest a little more on controls there and implement a quota system based on the numbers leaving.
