Juncker warns Britain - "No more negotiations"

European Commission President Jean Claude Juncker believes the time for creating a new deal is done, and Britain will have to settle for whatever the result of tomorrow's historic election will be.

"It is time for us to show our courage and our commitment to democracy by standing up to these unelected tin-pot figures."
