A spokesperson for the Home Office has said that the government's "tough new rules" on immigration are already taking effect.
The spokesperson said:
By introducing major reforms to work, student and family immigration routes we are tackling abuse of the system and net migration is falling, with the number of visas being issued at its lowest since 2005.
In terms of European immigration, the Government has made clear it will always apply transitional controls on new EU member states. We are also working to cut out abuse of free movement with other member states.
