LONDON (Reuters) - Britain continues to be hopeful that it can secure a trade agreement with the European Union but there are still gaps on key issues, a spokesman for Prime Minister Boris Johnson said on Monday. “We remain hopeful of reaching an agreement ... No deal is a possible outcome ... But we’ve been clear that we will continue to work to reach a free trade agreement,” the spokesman told reporters, repeating that fisheries and fair competition guarantees were areas where gaps between positions remain.
