Incidentally, there are plenty of Labour MPs exasperated that the whole issue of Brexit is a major public talking-point again. “It’s mad. The referendum decision has to stand,” one minister said to me. “I know what plenty of Labour Party members are like. They think the country got it wrong and they’d love to reverse Brexit. But it makes us look very detached. Improve Brexit, sure, but let’s not get into overturning it, for goodness sake.”
