FF Mark Daly is the one saying that Madigan informed him at a meeting on April 3rd 2019 about this. Madigans tweet, if you read it, doesn’t deny what Daly is saying. He didn’t mention what the meeting was. She’s also mentioning that she never ‘put plans’ to the All Party. That’s quite different to what Daly is saying. From what I read of Daly, the decision was already made, so of course there wouldn’t be plans to do it.
Daly is saying in she told him. (‘Him’ as in singular). She is trying to present it as he having said she had ‘not’ told a meeting of a number of people (plural).
A solicitor seeking legal advice? That’s like a blocklayer with 20 years experience asking how to mix cement.
