David Cameron speech on welfare
25 June 2012 Last updated at 12:25 BST
David Cameron is considering bringing in regional rates of benefits, as part of a "wider debate" about welfare.
No 10 says the prime minister wants to look at whether "it makes sense" to set benefits at a national level, given differing regional pay levels.
During a speech in Kent, the ideas are expected to be ones for the next Tory manifesto, rather than for the current coalition government.
