So have we been through a bit of a learning curve here? And so he's able to do policies now, put forward ideas that maybe 10 years ago would have been lambasted, but now we've perhaps learned from experience a little.

Well, two things there.

The policies that Jeremy Corbyn promoted about nationalising certain key industries, and the railways in particular, were always fairly popular with the public, actually.

So even those that didn't like Jeremy Corbyn thought some of the arguments about the way the private sector was running things in certain places really wasn't working.

So I think what we have here is a prime minister who understands the need for a more strategic state that can join up different policy areas in ways that haven't been able to do in the past.

And the thing is, and again, what a lot of commentators I think are missing is this isn't all about Andy Burnham.

British politics today isn't about the new Labour government.

He's got to fight thinking like that at every level, hasn't he?
