David Cameron is reported to have made "really good progress" on an EU reform deal during this week’s Brussels summit but warned it would take hard work to get an agreement by February as hoped. Mr Cameron said EU leaders had agreed to work with him on all four areas of his reform demands, including his controversial call for a four-year limit before EU migrants working in Britain can claim welfare payments which EU leaders had previously said was "unacceptable”. The three main other demands are to ensure greater protection for non-eurozone Member States, an exemption from the EU's goal of "ever closer union" and greater economic competitiveness. In its conclusions, the EU leaders said that after a "substantive and constructive debate" they "agreed to work closely together to find mutually satisfactory solutions in all the four areas at the European Council meeting on 18-19 February 2016".
