Hands up those who remember when Crispin Blunt resigned from the Conservative frontbench.
Yes it wasn't exactly the most memorable event in recent political history. Blunt resigned literally when the local election polls closed and called for his party leader to go, expecting lots of MPs to sign letters. The political chatter assumed that his leader was doomed there and then. Instead the whole thing fizzled out, hardly anyone signed a letter there and then and things went on as normal for the time being.
The parallels with James Purnell's resignation are obvious. Over the past few days we were hearing about a round robin letter being anonymously circulated with loads of cloak 'n dagger stuff. Now I turn on the television to hear that the voices in the darkness are holding back on the letter and it may well never go ahead at all. After a few weeks I wonder if anyone will even remember this. The coup has been Blunted.
Of course Iain Duncan Smith did fall some months later after further events, including signs the party was going to crash into third place. If the parallels continue then Gordon Brown may well find a threat that's Betsygated...
