Obama Congratulates Britain's Cameron on 'Impressive' Election Win

U.S. President Barack Obama on Friday congratulated David Cameron on an "impressive electoral victory," after the British prime minister secured a new term in power.

"The special and essential relationship between the United States and the United Kingdom is rooted in deep and abiding shared interests and values," Obama said in a statement.

"I have enjoyed working closely with Prime Minister Cameron on a range of shared interests these last several years, and I look forward to continuing to strengthen the bonds between our countries."

Cameron's Conservative party won victory, despite widespread predictions of a tie with the Labor party. 

Cameron has promised to hold a referendum on Britain's European Union membership in 2017, a vote that could have profound repercussions for the country's role on the world stage.
