The Labour old guard spent their Sunday afternoons locked in a bruising Red on Red deathmatch. The protagonists: Blairite Shadow Cabinet minister Ivan Lewis and one time Brownite bootboy Tom Watson. The subject: Scottish Labour’s leadership election. The venue: Twitter.

Seconds out!

@IvanLewis_MP presumably you'd rather they quietly elect your candidate whilst we all watch. Plus ca change.

@IvanLewis_MP how interesting. Which ones do you think I manipulated?

@IvanLewis_MP do what again Ivan? You haven't specified your allegation.

Alas, Ivan couldn’t quite bring himself to write ‘knifing Blair’…
