Seems like the end of the road for Ken and Trev's relationship - they just can't seem to kiss and make up.
Ken Livingstone's long-running feud with Trevor Phillips, the outgoing chairman of the Commission for Racial Equality, escalated yesterday when the London mayor refused to participate in the watchdog group's race convention.
Mr Livingstone explained his decision to boycott the event, which begins in London today, in an outspoken letter to Mr Phillips.
Is it me, or does anybody else find Livingstone's pathetic sulking a bit - well, childish? Isn't it about time he started behaving like an adult, not an over-indulged and spoilt brat
He claimed that workshops with titles such as "Rivers of Blood, did Enoch Powell get it right?" were designed to grab alarmist headlines rather than develop sensible discussion.
Well, Ken would know all about "grabbing headlines" - though I'm not sure he's quite so qualified to comment on what constitutes sensible discussion.
He said Mr Phillips's credibility had already reached an all-time low among those who had been the victims of racism.
Seeing how recent reports have indicated that white people are more likely to be victims of racism than any other group - I seriously doubt that. But to people like Ken, white people can't be victims - only victimisers.
The London mayor had been angered by Mr Phillips's own warnings that Britain was in danger of "sleepwalking to segregation". But Mr Phillips's supporters believe that the London mayor has been stuck in a 1980s time warp. "He thinks we should still be out on the streets shouting that it is all the white man's fault," said an ally last night.
It's always rather sad when a relationship falls apart - but not for the normal reasons in this case. Watching two arrogant and self-obsessed lefties bash each other up as they squabble over the crumbling remnants of their multi-culti ideology would be rather amusing if it wasn't for the fact that they are both very influential and powerful people and the even more significant fact that while they argue over who is more PC and "right-on" Britain and London continues to slide into ever greater depravity, chaos and distress.
One day our grandchildren will look back on these times and say "What the hell were you lot thinking?"
