I've not followed this story much, and I have little interest in it.
However, it does smack of The Sun looking for another Philip Schofield who can be dragged in to the street and beaten with sticks by the mob.
When there has been a big story, it's not uncommon for the media to go looking for something similar to follow it up. It's also not unknown for family members to see this as an opportunity to cash in: the Shannon Matthews story followed hot on the heels of the McCann case.
The Sun is criticised, and rightly so, but we get the media we deserve, and if there wasn't a market for this rubbish, it wouldn't exist.
