I'm really surprised that McDonnell didn't think how badly this could go for him, it's obviously going to be presented not as "Shadow Chancellor makes cutting joke about Osborne's friendly relationship with China" but "Shadow Chancellor quotes Mao".
I know the super slick New Labour style isnt in favour anymore, but really, there must be a middle ground... or is this actually a really clever plan I'm not seeing?
