Labour MP Sion Simon’s spoof on David Cameron’s venture into cyberspace (through which he appears determined to cultivate a nice-but-dim image) may win the headlines, but it is embarrassingly bad. It shows that 640-odd MPs is about 440 too many: there really is very little work for backbenchers to do. On the other hand, this video from Bloggerheads hits the mark. Bloggerheads lost its satirical edge about the same time the failed Backing Blair campaign fibbed about technical sabotage and went all anti-Trade Union. But this is a return to form… a simple joke well executed.
