So, The Sunday Times reporting that Mr De Peffel Johnson was a "frequent visitor" to the home of Jennifer Arcuri. And that she described him as "one of her best friends".
She was also included on three trade missions he went on as Mayor, despite seemingly not meeting the criteria for some of the trips, and thus being included apparently at his teams personal request.
There's also a question of grant payments to her of around £125,000 (£10k from a GLA fund of some sort whilst Johnson was mayor, £15k from central gov in 2014, and a further 100k for UK based businesses this year, despite her having moved back to the US in 2018).
And then the Sun (spit) steps in to ask Johnson if he was having his end away with her and he refuses to answer the question 3 times.
I have no idea if this is true yet, but he's not exactly got great form on either side of this really. What's kind of interesting to watch is that previously it's all been a bit water off of a ducks back. If it is true, will it stick this time, given the greater responsibilities he now holds?
Also, plenty of people also pointing out that even as Mayor, Johnson was being spoken of as a future PM, and made little secret of the fact he would like to be, and that this is just the sort of info that foreign intelligence agencies like to pick up and hold onto. And that even if it's all above board, the optics aren't exactly great.
