Well, to me that's the thing, I don't see that it is a legitimate attempt to undermine him. What it was, in my opinion, was an attempt to smear by association. I genuinely don't think they came close to a question to be answered, or an issue debated. It seems to me that they used their medium to veer into an area where they had no genuine journalistic intent, other than to sling shit and hope some of it stuck to his son. I didn't see any real attempt to link the story to any concerns they had about Ed Miliband.
