It's an affair which has 'stunned' people in Downing Street and could have huge repercussions for our Prime Minister David Cameron.
So much so that the Mail on Sunday quoted the line that Mr Cameron ‘immediately realised the importance of the story'.
The Mail also added: “David Cameron holds crisis talks at Downing Street after being told of the alleged affair which has potentially significant political implications for him.”
Yet amid all the rumours there were demands for the names and accusations Downing Street and Mr Cameron had told the Mail on Sunday not to run something.
Rubbish, do you really think a Conservative-leaning newspaper would have run this unless they knew the damage it could do to Mr Cameron who is hardly their friend at the moment.
The simple truth is the Mail on Sunday ran as much as it could do by law, there is no junction or super-injuction preventing the MoS spilling the beans but other legal reasons.
As I tried to state last night, newspapers are governed by a variety of laws and restrictions and cases like this show how responsible the industry can be.
The names of the two rumoured to be involved are rather widely found now on the internet and social media.
I would imagine the Mail's lawyers are working on a way around the legal restrictions as I write this as a result.
Even though this is a personal blog, I abide by the laws covering my profession so I won't reveal the names.
But if the rumours are true and they are indeed the two people involved, our Prime Minister will have a huge headache.
