This may prove to be as accurate as my 2008 "Thatcher no more" post, but a Twitter source claims Steven Purcell is resigning for personal reasons (not to stand for Westminster as had been rumoured).
If it's true, especially if he really has "jumped before he was pushed", this is a serious blow to Labour. He's been running Scotland's largest local authority, one of the few remaining Labour-only administrations.
He's also long been touted as a future LOLITSP, and constitutes approximately 100% of the party's rising stars in Scotland.
Let's see what tomorrow's papers hold. The full story is apparently due then.
