He plans to run things as a center or light center-left. That... was hardly a secret even to me a full ocean and a half away.
Dunno why it would be a surprise to anyone, honestly.
Noting he has said or done in the last year says Keir Starmer is centre left to me. He’s centre right at best, given that he seems to be to the right of Ireland’s centre right parties.
The US "center" is very right-wing by international standards. By British standards, Starmer is very much centre-right. He's basically David Cameron without the aristocratic lineage.
