The excellent English Crusade blog posts that, according "to the Office for National Statistics, the Labour party have presided over the largest wave of immigration this tiny island has ever seen."
The report actually fails to tell the whole story concentrating only on foreign "workers" and ignoring the thousands of illegal immigrants, foreign "students" and asylum seekers who do not work - either officially or unofficially.
The vast majority of these immigrants have settled in the South East of England which is currently experiencing a "drought" - judging by the amount of rain we've had over the last few months, quite probably the wettest drought in history.
I don't doubt that there have been periods of lower than average rainfall over the last couple of years, but this is nothing unusual. However, without the extra demand caused by so many extra people needing this resource, I'm sure that water levels would have recovered by now.
That's the trouble with just considering immigration as simply an impact on the balance sheet (even that is dubious). No consideration has been given to the impact it has on the infrastructure of the areas where immigrants move into. It is surely no coincidence that we are suffering a supposed shortage of water at the same time as we are undergoing the largest wave of immigration ever known to these tiny islands? (Pun intended).
