After all, how else to explain Ed Miliband in his speech on being elected Labour Party leader disparaging people who used terms such as “Red Ed” – saying “Come off it. Let’s start to have a grownup debate in this country” – and then Harriet Harman today going for her own bit of ‘red’ political labelling, calling Danny Alexander a giant ginger rodent?

After all, to ignore her own party leader’s call for people to grow up would be a bit of a snub for Ed Miliband from Harriet Harman. So she must have fallen asleep and not heard him say that. Right?

Nice response on Twitter from Danny himself by the way:

UPDATE: More on this story over on Andrew Reeves’s blog, including the news that Harriet Harman has sent a press officer off to apologise on her behalf.
