Barack Obama, US President has called on Britain to stay in the European Union, cautioning remaining in the bloc was necessary to help preserve the nation's global influence.
Obama's comments, during an interview with the BBC aired on Thursday, come ahead of a planned British referendum that will determine whether the country remains in the EU.
"Having the UK in the European Union gives us much greater confidence about the strength of the transatlantic union," Obama said.
"We want to make sure that the United Kingdom continues to have that influence."
Obama went on to refer to the EU as a "cornerstone of institutions built after World War II" that has helped make the global community "safer and more prosperous".
Conservative British Prime Minister David Cameron has promised to hold a referendum on the country's EU membership by the end of 2017.
