'An explosion in the number of non-EU students allowed to stay in the UK is adding 100,000 to the population every year, figures show.

The number of foreign students granted permission to stay for a year or more has trebled to 110,000 a year since Labour came to power.'
But annually only 10,000 go home - a ratio of 11 arrivals for every departure.
