LONDON (Reuters) - Britain is prepared to leave the European Union’s orbit without a trade deal with talks at a critical moment, British minister Penny Mordaunt told parliament on Monday. Mordaunt said there had been some progress in negotiations but familiar differences remained, with the so-called level playing field issue “the most difficult”. “While an agreement is preferable, we are prepared to leave on so-called Australian-style terms if we can’t find compromises,” she said.
