Boris Johnson’s chief advisor and his family are liable to pay council tax for properties on their Durham farm – but years of previous history will not be backdated

Dominic Cummings and his family are liable to pay council tax for properties on their Durham farm – but it will not be backdated.

It means that years of unpaid taxes on two homes will be written off.

Instead, new charges for the properties will start this month following an investigation by the Valuation Agency Office.

Durham County Councillor John Shuttleworth attacked the move, saying: “They should have informed authorities and it should have been checked.

“If it was anybody else, they would be getting charged and it would be backdated.

“It just proves there are two sets of rules, one for them and another for everyone else. It is not right.”

Planning documents suggest a cottage was built on the farm owned by Mr Cummings’ father in 2002.
