Outgoing U.K. Prime Minister David Cameron is attending a European summit in Brussels on Tuesday where pressure is expected to be applied on the U.K. to trigger Article 50 to start the process of leaving the European Union (EU).
EU leaders are expected to debate the U.K.'s decision last Thursday to leave the economic and political bloc made up of 28 countries, which has prompted turmoil in global markets and crisis in the political establishment, both in the U.K. and EU.
However the U.K. has yet to trigger Article 50 which begins the leaving process despite calls from other EU leaders to do so – meaning that the summit could be acrimonious.
Cameron said he wanted a "constructive" divorce from the EU on arrival in Brussels.
"Britain will be leaving the European Union but I want that process to be as constructive as possible and I hope the outcome can be as constructive as possible," Cameron said.
