Nail on head.
They should be made to answer any questions put to them, or they may as well scrap the meeting as it's pointless.
Totally agree. It's a separate point to the thread I suppose, but what is the point in the speaker if they don't ensure that the house (and the electorate) get proper answers to questions? It's an utter pisstake that the PM can be asked a direct question and respond with some meaningless waffle and then a pre-prepared counterattack line that is either misleading or completely irrelevant.
