Migration rise: 'Build Birmingham every 2 years'

New figures show there has been a significant increase in net migration - the difference between the number of people coming to live in the UK and the number emigrating.

Last year, the figure was 239,000, a rise of just over 20% on 2009.

The government has promised to reduce net migration to below 100,000 by 2015.

Sir Andrew Green, from the think-tank Migrationwatch UK, said the latest figures represented a worrying trend.
