Dominic Cummings, the Prime Minister’s chief strategist, is facing calls to resign after the Guardian and the Mirror revealed that he travelled from London to Durham to self-isolate with his parents after developing the symptoms of the novel coronavirus.

Government sources have told the BBC’s political editor, Laura Kuenssberg, that Cummings did not violate rules because he went to his parents so they could help with childcare while they were ill.
