You having a giraffe?
At first I thought His Daleness had fallen through some kind of April Fool wormhole, but no, it really looks like Labour think that comparing "Dave" to Gene Hunt is a good idea.
Bear in mind I've only seen Life on Mars series one, but I understand it's the same character. I'm a tofu-eating former roads protester, and this is not a damaging comparison. I liked 1970s bad apple Gene Hunt a lot more than his do-good time-travelling colleague.
Second, it's a working class role, or it was. It's undermining all those "can't trust a posh boy" pseudo-class war messages Labour are trying to run in the background.
I may have missed the point, and there may be nothing whatsoever left to like about Gene Hunt by the time we get to Ashes to Ashes. But this looks like some kind of weird dummy, like Labour have designed a notionally people-led campaign to go wrong simply so Cameron's face can be everywhere for four days.
I can see no other explanation. If they wanted to tie Dave into the dark days of Thatcherism and remind us of how dark they really were, they'd surely have used a version of this image instead:
