Before we get to that, a brief thought on the PM and his amendments to the Ministerial Code. At the heart of most scandals is a conflict of interest: putting your own personal interests ahead of those you should take into account. The PM is ultimately responsible for the Ministerial Code and its enforcement. How is that supposed to work when it is him accused of breaching it and he is under investigation? He should not be judge and jury in his own cause. Nor should he be rewriting it while under investigation. But that is the system we have. It has only worked because PMs have, on the whole, been Good Chaps who understood the need to try and abide by it and, crucially, understood the need to abide by agreed conventions and restraints on Prime Ministerial power. Boris is not such a Good Chap. So, once he goes, matters will snap back to how they were before, right? Not so. It would not matter if the PM was the Archangel Gabriel with the wisdom of Solomon. The conflict of interest is still there. How to resolve it? An independent regulator with the power to initiate investigations? A court? And how does this fit with the fact that the government has been elected? This tension has been highlighted by the PM’s behaviour but it will still be there when he is gone. Among all the sound and fury, this issue has barely been addressed let alone resolved.
