Thanks Royston.
The page was updated last April.
This was the situation then.
5. Foreign immigrants are now arriving at the rate of about ½ million a year - or nearly one a minute. Allowing for those who leave, net foreign immigration reached 333,000 in 2007.

6. Meanwhile British emigration has risen in recent years and was 96,000 in 2007. This gives a net increase for 2007 of 237,000. These current levels of immigration are 25 times higher than at any time in our history (Briefing Paper 6.1).

Unprecedented indeed!
25 times higher no less.
What would that be down to now Royston?
