Britain's representative on the EU's executive body says he is resigning because it would not be right to carry on after the U.K. vote to leave the bloc.

Jonathan Hill, Britain's EU commissioner, says he's very disappointed by the referendum result, but "what is done cannot be undone."

Hill says in a statement that he will work with EU Commission President Jean-Claude Juncker to ensure there is an "orderly handover."

Hill says he started his job skeptical of the EU but leaves it "certain that, despite its frustrations, our membership was good for our place in the world and good for our economy."
