Apparently Sussex friendly journey, Charlotte Griffiths, the MoS reporter who broke the story of the meeting, was tipped off about it the week before. When asked by GB news how she came across the story, she says:
" Here we are at the beginning of the end of the feud. That's all I can say. I never thought I would say these words on your show. What my sources were telling me, what they were telling me all week, was look out because a big meeting's coming and the meeting is significant. Although they didn't have a specific agenda, very much rapprochement was on the cards...that was the word on the lips of my sources, that's all we're after. It's getting the conversation going again between these two warring sides, opening the lines of communication and the very first step on the pathway towards the end of the feud."
I think we can be pretty clear where the leak has come from.
