PM Cameron still wants welfare changes in EU talks - spokeswoman
Cameron has promised to reform Britain's ties with the 28-member bloc before a membership referendum by the end of 2017 but his welfare demands have proved a problem for eastern European member states.
On Thursday, Poland said it had not been able to reach agreement with Britain on the plan. Cameron's spokeswoman said he was open to discussions with EU leaders about finding a solution to the issue.
