Maybe my memory is going (it is!) but something quite strange happened on the BBC news last night. There was a report about Tony Blair's speech telling the Labour party that lurching to the left would make them unelectable. This was followed by a whole series of young Blairites (who didn't look old enough to actually remember the birth of New Labour) spouting the same line. Then we cut to Jeremy Corbyn describing how Blair destroyed the Labour party and involved us in the "disastrous and illegal Iraq war".

It seems like a long time since a major UK politician has described the Iraq war as "Disastrous and Illegal".

Blair's suddenly looking old, but he looks just as driven and criminally insane as ever. And this unshakable belief in a New Labour that is a lite-clone of the Tories is increasingly bizarre. It's not enough to have failed to learn anything from the last 20 years, he apparently wants to keep pulling the Labour party to the right and into a lacklustre place where it's indistinguishable from, and provides no real opposition to, the Tories. In which case, why vote for them?

It feels like this struggle for the soul of the Labour party might easily produce another split like the one where the SDP broke away. Perhaps this time it will be the Left that leaves and gets absorbed elsewhere rather the the Centre-right.
