What happened to those defections to the Tories?

A few people have asked me, both in comment threads and elsewhere, what has happened to the announcement on two Lib-Dem councillors defecting to the Tories, which I caught wind of on Friday.
An announcement was expected today, but I now understand it will be tomorrow at the earliest.
And from what I have been told by the Tory orchestrating the whole thing, the surprise element may not be all it was cracked up to be. It’s more complicated than first thought.
Will update when I know, but not sure it’s a gamechanger, as they say.
