Jeremy Corbyn faces an interesting choice – will he demand that the people decide?

For many months Labour's leaders have hedged and fudged and dodged on the subject of a new referendum on Brexit. Now Jeremy Corbyn must make a decision to commit to a second referendum. There are arguments of principle and tactics for making the promise clearer and more emphatic. The argument of principle is that a new referendum is the only democratic way to resolve the Brexit morass. Parliament and the nation are now divided three ways, between leaving the EU with a deal, leaving without a deal, or not leaving at all.
