New Foreign Secretary Philip Hammond has insisted he will not be "threatening" other EU states as the UK seeks to renegotiate its position in the bloc.
Mr Hammond is seen as a more eurosceptic voice than his predecessor, William Hague.
"I'm going to focus on making sure that we have a successful renegotiation with our European partners," he said.
"I don't think the way to enter a negotiation is to start issuing threats."
