LONDON — British police say Prime Minister Boris Johnson’s adviser Dominic Cummings likely violated rules by traveling from home during lockdown, but the force has “no intention” to pursue the matter.

Cummings has acknowledged driving 250 miles (400 km) to his parents’ house in Durham, northeast England, during the lockdown, and later taking another drive to a scenic town 30 miles (50 kms) away.

Durham Constabulary said Thursday that the second drive, to the town of Barnard Castle, was probably a “minor breach” of lockdown rules that would have “warranted police intervention had he been caught in the act.” But police say there is “no intention to take retrospective action.”

Johnson has resisted calls to fire Cummings for apparently flouting restrictions the government imposed on the rest of the country.
