Any situation which makes Boris Johnson come out looking good has almost got to be a PR disaster for someone. And in the case of the abortive Super League plan to create a breakaway members-only club for European football’s elite, the UK prime minister looks to have scored at the expense of private equity. Of course, the asset class isn’t the only reputational casualty. All the same, the Super League shenanigans can only have fuelled ill feeling in a region where private equity is already distrusted and disliked by large swathes of both the public and the political elite.
