What were the UK lockdown rules when Johnson’s chief adviser allegedly broke them?

Dominic Cummings allegedly violated the measures by travelling 260 miles from his London home to his family home in Durham.

When Boris Johnson introduced the UK lockdown he gave “a very simple instruction – you must stay at home”.

But it has now emerged his chief adviser, Dominic Cummings, allegedly broke the rules just days later by travelling 260 miles from his London home to his family home in Durham.
