I have noticed recently that the Speaker, John Bercow has been going further and further in trying to control the baying mob at PMQs. There is still barracking and heckling but when it gets too much he is more frequently stepping in and embarrassing individual members who are behaving badly even threatening to sin-bin them. He also keeps pointing out how most people watching outside the chamber find this sort of behaviour very off-putting.
