David Cameron promises 'one last go' at EU migration curbs
David Cameron has said action is needed to curb EU immigration and pledged to have "one last go" at negotiating a better deal for the UK in Europe.
Speaking in Kent, where there is a by-election next month, he said: "We need further action to make sure we have more effective control of migration."
Last week the Conservatives lost a by-election to the UK Independence Party, which wants the UK to leave the EU.
Lib Dem Nick Clegg accused the Tories of "blind panic" at UKIP's rise.
