There can be no better description than the word vacuous to describe the performance by the Leader of Her Majesty's Opposition, David Cameron, on the Today programme this morning. I have crticised Tony Blair more than most over the last decade... but the very notion that this silly public schoolboy Cameron could lead the country is barely credible. Thatcher was brutal, Major was boring, Hague and IDS were joke figures, Howard had substance, though people just didn't like his substance, but Cameron is just.... well, vacuous!
It certainly seems like the old duffers at The Telegraph are getting worried:
Mr Cameron's ill-judged sally gave John Prescott the opportunity to wallow in righteous (and wholly artificial) indignation, describing the Conservative leader's remarks as "beyond belief" at a time "when we should all stand united". Political sanctimony from Mr Prescott is hard to stomach, but it has to be said that Mr Cameron left himself wide open to the attack. We trust his future musings on these complex issues will be both more thoughtful and more memorable.
