Yet we have learned from the Scottish independence vote and with Brexit what referendums do to our politics. They foster bitter divisions in ways that parliamentary elections tend not to do.

Being on the left is supposed to be about unbounded optimism, a belief that what is deemed politically impossible by the 'sensible grownups' of politics can be realised, with sufficient imagination and determination.

A society should be judged by how it treats its children. A country that fails to invest in its children is imperilling its future.
