West Midlands MEP James Carver is pressing for David Cameron to campaign to leave the EU after failing to achieve even minor treaty changes he demanded.
“My role is to stand up and be counted for the people of this region and I hope Cameron has the back bone to do the same,” said Mr Carver, UKIP Euro-MP.
The Prime Minister has been told that EU leaders cannot agree on his demand to ban EU migrants from claiming benefits for four years.
In a letter to the European Council, the President of the European Council, Donald Tusk, said Mr Cameron had raised "difficult" issues in his demands to reform the UK's deal with the European Union.
Mr Carver said, “President Tusk has plainly called Cameron’s bluff.
“We have been told we will get no substantial change on welfare benefits for EU migrants. It is up to Cameron to now follow through on his threat to campaign to leave the EU as he has not received even the minor changes that that he asked for.
“Given the refusal of those in Brussels to countenance meaningful changes in Britain’s relationship with the EU, the only honourable avenue left to David Cameron is to now campaign to leave. He put out that signal recently to EU leaders and must now follow through on his word.
“In this so-called renegotiation, Cameron asked for no meaningful changes, and that is exactly what he received. Britain deserves better than this,” said Mr Carver.
