Ed Miliband wasn't asked about the cost of the average weekly shop, he was asked what his family spend. Not the same thing by any stretch, and as such you blur two unrelated issues
If he has no idea of his own weekly shop how can he compare himself to others, how can he be real and with one of the people.
Lets say, he has no idea about heating, food, wages, petrol....and so on, fine but all of the prices of these things are the vital cogs of our lives, every day...
Great ED has no idea about these things, fine, just don't say your one of the people or getting tough on the financial crisis, because the reality is, your a stuffed puppet, but a rich puppet with no idea of peoples every day lives... being dragged around, told to say your getting tough on..real issues your working class fan base is facing.
