Tomorrow, it is expected that the UK will have a new Prime Minister. Whoever is appointed will have a number of high priority issues competing for their attention. Peter Riddell argues that constitutional standards should be near the top of the new PM’s to do list. He calls for a new Independent Adviser on Ministers’ Interests to be appointed, and warns against interfering with the Privileges Committee investigation into Boris Johnson.

The new Prime Minister is going to have such a large in tray of urgent decisions that there is a danger that the ethical and constitutional issues that largely brought down Boris Johnson will be neglected. There is an even worse risk that the wrong lessons will be learned from these events and that the future standards regime will be weaker than before, particularly over the Independent Adviser on Ministers’ Interests.

During the regional hustings meetings of the past few weeks, there have been hardly any references to the controversies over standards that so dramatically undermined Johnson’s position among Conservative MPs. As striking, and worrying, have been the recurrent attacks by Liz Truss’s supporters on unelected advisers and regulators, whether the civil service, the Bank of England, City and business regulators, or ethical watchdogs. In particular, while Rishi Sunak has said that he would quickly appoint a new Independent Adviser to fill the vacancy left by the resignation of Lord (Christopher) Geidt in mid-June, Truss has been more equivocal.

Truss has so far refused to commit to appointing an ethics adviser, arguing that she personally has ‘always acted with integrity’ and understands the difference between right and wrong. She has said that ‘one of the problems we have got in this country in the way we approach things is that we have numerous advisers and independent bodies, and rules and regulations’. While she would ‘ensure the correct apparatus is in place so that people are able to whistle-blow’, she believes that ‘ethics and responsibility cannot be out-sourced to an adviser’.

This view confuses the roles of advisers/regulators and ministers. In the case of the Independent Adviser, there is no outsourcing of ethics and responsibility. What the Adviser is being asked to do is to establish the facts about whether the Ministerial Code has been broken, while an elected politician, in this case the Prime Minister, decides whether a minister should be punished and what form any sanction should take. In that sense the Prime Minister is the guardian of the final judgement on ethics and responsibility. And there is now general agreement that there should be a range of sanctions, and not just resignation.
