On a morning when polls show that Labour are at a record low with the electorate, Mr Blair took the opportunity to attack the Tories, calling them ‘confused’.

Every time they are called on to make a big judgement call on policy, they misfire. New Labour made the Tories lose their bearings and this new Tory leadership has not found them. From law and order, to NHS reform, to taxes on the environment, they just get it wrong.

Politics is cyclical. New Labour, with the help of Mr Blair, introduced a breath of simplicity to the system. He brought us back to black-and-white, good-and-bad, right-and-wrong politics, which fitted with a popularism for that kind of thinking in the country at large.

Mr Cameron has reintroduced the era of nuanced politics. The era of greys, where some parts of something can be right, while other parts are wrong. An era where decisions are difficult and finely balanced between benefit and risk. And, once again, we’re starting to see a popularism with that sort of thing in the country at large.

Mr Blair rubbishing all of Mr Cameron’s ideas as without merit belongs to an earlier political era, and makes him look silly – especially when Mr Cameron is capable of working with the government on parts of plans he believes are right.

It’s startling to see a Grand Master of the political game suddenly unable to keep up with a new young upstart.
