BORIS JOHNSON’s government was rocked this morning by a ministerial resignation over the Prime Minister’s senior adviser Dominic Cummings’s conduct during the coronavirus lockdown.

Scotland parliamentary under-secretary Douglas Ross said that he was quitting after hearing Mr Cummings’s statement on Monday, in which he defended his 260-mile road trip from London to Durham while the nation was told not to travel.

Mr Cummings said that he and his wife, journalist Mary Wakefield, both felt ill from suspected Covid-19 and had driven with their son to Durham on March 27 to stay on his father’s farm.
