Nadhim Zahawi’s family lived ‘in breach of planning condition’ at Cotswolds mansion

The ROC stated that occupation of the property was limited ‘to a person solely or mainly working, or last working’ in local equestrian activities, agriculture or forestry.

Documents show that the planning clause was inserted because “planning policies would not support the construction of a new dwelling for unrestricted occupation”.

Mr Betts, who represents Sheffield South East for Labour, added: “People make an awful lot of money building houses in attractive areas. I understand why these sort of rules apply – they are important in rural communities to ensure there is housing for rural workers.

“There’s a very simple rule – members of parliament shouldn’t behave in a way in which ordinary members of the public shouldn’t behave. They should be very careful to make sure they comply with all the rules around planning.”
