Tina Brown has a point re Murdoch press, Princess Diana. Why no UK interest?

I am repeating an earlier post but this is still a puzzle. There is interest in News of the World at the moment, with a Guardian Editorial calling for more investigation.

Last year Tina Brown published a blog asking about an earlier occasion when a phone tape of Princess Diana became available. She suggests that the conventional explanation is not the only one.

I am surprised that the blog post is not commented on. I cannot find other UK blogs that have linked. 

I am not going to get into the issues around how the original Squidgygate story came to be published or the plausibility of whether a radio ham would happen to overhear a particular conversation. But I will try to follow up whether other UK blogs check this out. Surely the Daily Express would welcome another Diana story?
