BRUSSELS, BELGIUM - OCTOBER 24:  British Prime Minister David Cameron speaks during a press conference at the end of a two-day European Council meeting at the headquarters of the Council of the European Union on October 24, 2014 in Brussels, Belgium. Alongside criticism from outgoing European Commission president Jose Manuel Barroso on the UK's stance on EU immigration and a plan to quit the European Court of Human Rights, the UK has been told to pay an extra 1.7bn GBP (2.1bn EUR) towards the EU's budget because its economy has performed better than expected.
