Britain's prime minister David Cameron is having finance minister Osborne lead the negotiations with Germany and France on treaty changes for Britain to stay in the European Union, following his election promise to hold a referendum by 2017. The discussion about the prospects for changes show how difficult it will be for Britain to get the changes in the next 2 years. German chancellor Merkel supports Britain staying in the EU but only up to a point, and German public opinion does not show strong support for the kind of changes on immigration that Cameron is seeking. Support is also declining in countries like Poland because of the immigration issue. Merkel would like to see Britain in because of its open economy, free markets, and also because German contributions to the EU budget would increase significantly with the exit of Britain. Northern countries such as Sweden would also favor an effort to keep Britain inside the EU. On defence and foreign affairs EU without Britain would not carry the same weight and influence. Inside Britain Cameron faces problems with Euroskeptics inside the Conservative Party, and with the 13% popular vote that went to the UK Independence Party in the recent election. The uncertainty is not good for business and the economy of Britain, which is why Cameron is considering holding the referendum on the EU in 2016....
