Boris Johnson has today published a document in which his lawyers argue that the investigation into his conduct is unfair, something his allies say could endanger democracy.
Parliament's Privileges Committee is looking into whether Johnson, who is due to resign next week after his party ousted him over a series of scandals, obstructed parliament with comments on COVID-19 lockdown-breaking events in Downing Street.
If the committee finds he had misled parliament, Johnson could be suspended from the House of Commons, which could in turn trigger a so-called by-election for his seat, or electoral district.
