Dominic Cummings, Boris Johnson's chief advisor, remains in post tonight with a declaration of support from the Prime Minister following reports he broke lockdown rules to travel to Durham.
At this evening's press conference, Boris Johnson said Mr Cummings acted "responsibly, legally and with integrity", despite claims he went on a day trip to Barnard Castle and travelled over 200 miles during the lockdown period.
Mr Johnson said his advisor's actions were in keeping with the rules, which make provision for childcare emergencies.
