PM Cameron welcomes proposals to curb EU migration - spokesman

British Prime Minister David Cameron welcomes discussion of alternative proposals to his plan to curb welfare payments to European Union migrants but his original proposal remains on the table, his spokesman said on Thursday. The EU is offering Britain a new "emergency brake" rule that could give it the right to deny benefits to new EU workers for up to four years, sources close to the renegotiation of Britain's EU relationship told Reuters earlier.
