George Osborne, Britain's chancellor of the exchequer, will on Tuesday set out for the first time the UK's demands for EU treaty change to protect its economy, taxpayers and the City of London in a two-speed Europe.After months of diplomatic shadow boxing, Mr Osborne will use a speech in Berlin to set out in detail how Britain wants a new EU settlement to enshrine the rights of non-eurozone countries in the 28-member club.

"Quite frankly, the British people do not want to be part of an ever closer union," the chancellor will tell a business audience. "I believe it is this that is the cause of some of the strains between Britain and our European partners."
Mr Osborne will call for "principles embedded in EU law and binding on EU institutions" to govern a two-tier Europe, with an integrated eurozone surrounded by a looser group of countries using their own currencies.
