If it was significantly shorter it wouldn't have so good. It is the relentless piling of scorn and contempt, wave upon wave, that produces the result i.e. that the miserable Leader of the Opposition sits like a little lost boy who doesn't know what has hit him. He certainly never expected that from a PM who has no track record of such stinging attacks. He no doubt thought he was in a for little bit of peacocking for the entertainment of his backbenchers. It took him quite a while to twig that this wasn't how things were going to play out. Smashing theatre.
