The U.K.'s Prime Minister David Cameron said Friday morning he will resign, after Britain voted to leave the European Union in a hotly fought referendum.
Cameron had been campaigning for the "remain" side, arguing the U.K. would be safer, stronger and better off economically inside the union.
During a speech after the Brexit results were announced, the prime minister said the break-up negotiations with Europe need to take place under a new leader. The new prime minister will take over in October, he said.
"Leaving Europe is not the path I recommended," Cameron said. "I will do everything I can to help the U.K. succeed."
