Reuters are reporting that the 1922 Committee of Tory backbenchers has had the required 48 letters of no confidence in Theresa May to trigger a leadership challenge.
I don't think finding the 48 has ever been the issue, its finding the one that's willing to hold the sticky end of the stick, its the only reason why May is still in No. 10 and it still stands today.
Its the reason that all the "hard brexit" BS from Rees-Mog, Johnson etc is just that, BS. If they genuinely believed what they were saying, they could have been behind the famous black door and giving it a go a long time ago. But they aren't, because they don't.
For me, unless one of them is willing to put up, they should stop sniping like petulent children and do something useful... exactly what use they should be put to, I'm not sure.
