Cameron warned on blocking benefits to EU citizens

David Cameron has been warned that barring European Union nationals from claiming benefits in Britain would be “totally discriminatory” as he prepares to deliver a key speech on immigration.

The prime minister is said to be considering pledging a two-year block on handouts for new arrivals in a bid to win back voters from Ukip.

The pressure on MrCameron was increased when Home Secretary Theresa May admitted the government was “unlikely” to meet his target of cutting net annual migration below 100,000.
