Boris Johnson continues the will-he-won't-he suspense over his intention to run for London mayor. My view is that Boris would be a brilliant mayor for London and is certainly the only candidate who just might unseat Red Ken. Boris must know that his prospects as a national politician are somewhat limited: he is too much of a risk for David Cameron to promote to the Cabinet (assuming he gets the chance!).
On the other hand, the responsibilities of a mayor are much more suited to BoJo. He has the charisma and profile to promote the interests of the greatest city in the world; he is not restricted by collective responsibility; it doesn't matter too much how he feels about the inhabitants of provincial cities; as a Conservative mayor he will take a hands-off approach where necessary, allowing freedom to individuals and businesses rather than interfering in the minutiae and he is someone who genuinely engages with people.
