Boris Johnson was braced to potentially receive further fines for breaches of coronavirus laws after a justice minister resigned over the "repeated rule-breaking" in Downing Street.
Conservative peer David Wolfson said he had "no option" other than to quit because the scale and nature of the events determined by police to be breaches so far are "inconsistent with the rule of law".
Multiple newspapers carried reports suggesting the Prime Minister could receive further fixed penalty notices after he accepted a fine for attending a birthday party held for him in No 10 during Covid restrictions in June 2020.
