The story SO AMAZING ... we can't tell you anything about it
Well, this is unusual: A scoop SO BIG the newspaper with the scoop can't, you know, say anything about it.
According to the Mail on Sunday, Downing Street has been "rocked" by a "sensational love affair" that is "dynamite" and apparently Prime Minister David Cameron has been told about it by his aides and he was "stunned" and "immediately realized the importance of the story" and ... etc.
For legal reasons, the newspaper says, they can't publish anything about who the alleged lovers are or the details of the relationship - except that they're middle-aged.
You will note that today is Tuesday, and the news broke over the weekend. I held off writing about it, in part, because I was waiting to see what might come out in yesterday's papers. The answer: not much. Follow-up stories mainly focused on the fact that speculation was rife across SW1.
Now, I don't know who the alleged parties are, and my guess is that unless you're a Westminster insider, you won't, either - even when, or if, details come to light.
But this is a nice chance to have a chat about the Daily Mail and its Sunday counterpart. They are right-of-centre - which is kind of putting it mildly - middle-market papers, which make them a cross between a tabloid and a broadsheet. And they sell incredibly well; their circulation is second only to that of The Sun and the Sun on Sunday.
The Mail brand is powerful, the editors know what their readers want - stories about family, government, celebrity - and it's also a totally guilty pleasure (back when the Sunday papers in the UK were actually big broadsheets, I used to buy the Mail on Sunday and the now-defunct News of the World and hide them inside the very worthy Observer when I walked home from the newsagents. Then the Observer downsized and unless you buy the Sunday Times or Telegraph, which are still big, everyone knows what you're reading!)
Alas, there's no mention of the alleged Downing Street affair story on the front page incredibly successful - and completely time-stealing - Mail Online site today.
But don't worry. I'll keep an eye on it.
