McDonnell's been doing the rounds this morning
McDonnell reaffirmed Labour’s opposition to backing an interim government to stop a no-deal Brexit led by anyone other than Jeremy Corbyn. Asked to confirm that Labour would not support a vote in the Commons for someone else to lead an interim, cross-party governmnt of this kind, McDonnell replied: No, we won’t. We want to abide by the normal constitutional practice. Labour argues that, if the prime minister loses the confidence of the Commons, the normal procedure is for the leader of the opposition to be invited to form a government.
He did not rule out the Labour party officially being neutral in any second referendum on Brexit. Labour has said it would go into a general election promising a referendum on Brexit, with voters given the choice between backing remain and a credible leave option. McDonnell said he personally would campaign for remain. But asked if he would be happy for the party as a whole to be “agnostic” on the issue, McDonnell replied:
That’s one of the issues we’ve got to debate in the party. You know our democratic processes. I know people get frustrated with this ... but we’re a democratic party.
Although most Labour members want to remain in the EU, the shadow cabinet is deeply divided on this issue and there have been hints before that Corbyn could resolve this tension by allowing Labour members to take either side in a second referendum, with the party machine staying neutral. This is broadly the approach Harold Wilson took in the 1975 referendum. Recently Corbyn told the shadow cabinet that he had been reading a Wilson biography to learn more about how the then prime minister handled that issue.
