On top of his faux pas with Robert Flello (below) The Speaker actually forgot to call Nick Clegg to ask his question. After Cameron sat down he called a Labour MP, then he should have called Clegg. Instead he called Tory MP Nigel Waterson. During Waterson's question the Speaker's Secretary turned round and told him he had missed Clegg. But he then had to go to a Labour MP before he called Clegg. The Cleggmeister was apparently less than amused.
This Speaker is becoming a liability. As Betty used to say: "Time's Up".
