On 23 January 2013, Miliband stated that he was against holding a referendum on the UK's membership of the European Union because of the economic uncertainty that it would create. On 18 March 2013, Miliband reached a deal with both Cameron and Nick Clegg on new press regulation laws following the Leveson Inquiry, which he said "satisfied the demands of protection for victims and freedom of the press". In August 2013, following the recall of Parliament to discuss an alleged chemical attack in Syria, Miliband announced that Labour would oppose any military intervention on the basis that there was insufficient evidence. David Cameron had been in favour of such action but lost the ensuing vote, making it the first time that a British prime minister had been prevented from instigating military action by parliament since 1956.
