David Cameron rejects Cable immigration criticism

David Cameron has hit back at criticism by cabinet colleague Vince Cable over his promise to cut immigration to "tens of thousands" of people a year.

The Lib Dem business secretary said the prime minister had been "very unwise" and that such a target was Conservative - not coalition government - policy.

He added that Mr Cameron's comments, made in a speech to Tory activists, "risked inflaming extremism".

But the prime minister denied this and said his words had been "measured".
