Police say Dominic Cummings may have committed 'a minor breach' of lockdown rules when he drove to Barnard Castle. Prime minister Boris Johnson is standing by his senior aide despite Durham Police's findings.
The force has said that Mr Cummings will face no further action. A statement from Durham Police said Mr Cummings' trip to Durham to self-isolate was not considered to be a breach of regulations, however his later trip to Barnard Castle may have been.
Mr Cummings has previously said he took the trip to the town, which is around 30 miles from where he was staying, in order to check that his eyesight was good enough to drive home to London.
