“one of the key accusations that Starmer threw at Johnson in 2022 – and which he is now facing – is of misleading parliament, an act which the ministerial code of conduct deems a resignation offence.”

CORROBORATED

One web search result directly quotes an accusation that 'one of the key accusations that Starmer threw at Johnson in 2022 – and which he is now facing – is of misleading parliament, an act which the ministerial code of conduct deems a resignation offence.'

SINGLE SOURCE

The web search results discuss the controversy surrounding Mandelson's appointment and vetting, with one mentioning the issue of vetting advice. However, the specific claim that the scrutiny concerns Starmer appointing Mandelson *despite* vetting officials recommending denial is only strongly implied or stated in the search results, lacking multiple independent confirmations.
