I watched the Speaker live in on TV and the discussions that followed. It was not a pretty sight. Whilst the Speaker didn't fill in MP's claims and normally is not challenged, these are not normal times and it seems the Speaker has been active in gumming up the works - not his fault alone but his position is clearly untenable.
I think if he had reflected on his own role and stated he would stand down at the next election he would have shut the whole thing down. As it is the scenes from the Commons were surreal and painful.
