Theresa May, the UK's Home Secretary, has told the BBC that it will be difficult to meet the government's target of reducing annual net immigration to below 100,000 by May 2015 but has said that she will continue to strive to do so.
The target stems from a commitment made by the UK's Prime Minister, David Cameron, in 2010 when he was the leader of the opposition before the last election. The government has committed itself to reducing net immigration from its then level of about 250,000 to below 100,000 by the next election in May 2015.
