LONDON, Dec 3 (Reuters) – The trade talks between Britain and the European Union have suffered fresh problems because of disagreements about guarantees of a so-called level-playing field in any agreement on future ties, Sky News reporter Sam Coates said.

“The issue that’s causing problems is the most tricky one – the one both sides thought they’d nearly sorted – is the Level Playing Field – ie how close UK stays to EU standards,” he said on Twitter.
