We are told that Vince Cable, the Business Secretary, regrets unguarded comments made to Daily Telegraph journalists in which he indicated to his readiness to resign and, in so doing, apparently bring down the Government. Really? Either we are missing something or else Mr Cable has an exaggerated notion of his own importance a trait less uncommon amongst politicians than we would wish. Mr Cable is indeed free to resign if he so chooses and the Prime Minister accepts his resignation. Whether it would have a measurable impact on the fortunes of the Coalition Government is, however, an entirely different matter. We do not - and cannot deny that he's a clever man and that his skills, used in the right way, could bring immeasurable benefit to Government. During his seven month tenure as Business Secretary to date we are not aware though of any initiatives which have been of measurable benefit to business in the United Kingdom, particularly small businesses which account for a much larger share of the whole than is commonly acknowledged. In fact we very much doubt whether Mr Cable's department would be missed if it ceased to exist tomorrow. Regret, and indeed consternation, was expressed in some quarters when Mr Cable wasn't offered the Chancellor of the Exchequer's post. In the light of his latest alleged comments, perhaps the world has less reason to regret his failure to secure that particular post. What the country needs now is a strong, stable, Government somewhat better than the last one. If he is willing, Mr Cable has the opportunity denied to lesser mortals, to help make that Government a reality. Finally Mr Cable has made no attempt to conceal his dislike of Rupert Murdoch, apparently declaring war on the media tycoon and claiming that if it is in his gift to do so, he will attempt to block Murdoch's takeover of BskyB, an enterprise he partly owns anyway. We are no great admirers of Mr Murdoch and his empire. However we also very much doubt whether Mr Murdoch would employ Mr Cable to clean his shoes. If Mr Murdoch cannot have BskyB we don't doubt that he can and will find bigger fish to fry.
