No sign of Brexit reverse: 'The people of Britain have spoken'

British Foreign Secretary Philip Hammond and U.S. Secretary of State John Kerry gave strong indications Monday that the U.K.'s decision to leave the European Union is real and won't be reversed, despite the hopeful talk that emerged this week that somehow the vote might be reversed or delayed.

"The result last Friday is, of course, not the result that I wished for, and it means a difficult period ahead for our country as we adjust to the choice that has been made, and over a longer period, our economy adjusts to the new realities," Hammond said after meeting with Kerry in London.

"But the people of Britain have spoken and the government is clear that the result must be respected and will be delivered," he added.

Hammond played up the vote as one that doesn't mean Britain has to withdraw from the world, and said his country would continue to cooperate with the U.S. and other allies. That includes work to defeat the Islamic State.

But Hammond also made it clear that Britain needs to start thinking about how the rules might change for people moving between his country and others in Europe.
