David Cameron signalled new European battles ahead as he pledged to resist alleged attempts by Brussels to shackle the City of London in red tape. The Prime Minister echoed claims that the emergence of a two-tier Europe following the financial crisis could result in a wave of EU directives that would harm the Square Mile. The Government has said it is determined to prevent the 17 members of the eurozone acting as a bloc to thwart the interests of the 10 EU states, including Britain, that have retained their own currencies.
