A second ethics adviser quits, saying that the PM was pushing him to endorse a position of disregarding the ministerial code of conduct. Downing Street considers scrapping role.

So the ministers, up to and including the PM, do not observe customs regarding ministerial conduct. The PM has changed rules so that lying is no longer a resignable offence according to the code (and he'd ignored the customary action on that front anyway). The supposedly semi-independent advisers on ethics have quit.

What checks and balances are there on this government?
