Boris Johnson’s top aide Dominic Cummings was investigated by police after breaking the Government’s own lockdown rules, the Mirror can reveal.
The Prime Minister's chief-of-staff was spotted by witnesses at his parents’ home in Durham, more than 250 miles from his London property.
Mr Johnson and a string of senior ministers have repeatedly insisted the strict guidance is essential to slow the spread of the deadly disease and to save lives.
Mr Cummings started suffering from a bout of coronavirus at the end of March which left him self-isolating with his wife, journalist Mary Wakefield, and young son for 14 days.
