'Brexit customs union the only option left for Theresa May,' says Corbyn ally

Rebecca Long-Bailey made clear, however, that Mrs May will have to make a decisive shift towards Labour’s policy for a customs union. “I think, pragmatically, that they potentially may have no option in order to be able to push this deal through,” she told BBC Radio 4’s Today programme. A Tory source said the key question was whether Mr Corbyn and shadow chancellor John McDonnell “are willing to dip their hands in the blood of Brexit” and risk a split with pro-EU colleagues such as shadow Brexit secretary Sir Keir Starmer and deputy leader Tom Watson.
