Gordon Brown calls on pro-EU campaign to lighten up and ditch Project Fear

"In this debate, those of us who are supporting remaining in Europe have first of all got to be positive,” Mr Brown told a meeting of 100 leading economists held by the Centre for European Reform. "We have got to put forward the positive arguments." he said. He added: "People’s concerns are not just economic and financial but they relate to security and how safe they feel, and they relate to what kind of country we are becoming, our cultures, our traditions and what is happening on our borders."
