Andrew Rawnsley is spot on.
As an official, Ms Gray could not pass judgment on whether the prime minister and the cabinet secretary, her bosses, are fit to continue in office. The independent adviser on ministerial interests, the post currently held by Christopher Geidt, is not fit for purpose either. He can only investigate code breaches with the permission of the prime minister, who can simply toss aside the adviser’s verdicts, as Mr Johnson did when the previous adviser found Priti Patel guilty of bullying. Evidence can be kept from the adviser, as Lord Geidt discovered when he tried to investigate Wallpapergate. The remedy is to implement the proposal of the committee on standards in public life when it made 34 sound recommendations to improve the integrity of government. We must have a genuinely independent invigilator of ministerial conduct with the power to initiate inquiries, demand the production of evidence and publish findings in full without interference by Number 10.
