Tenant running car dealership
She has rented her property (effectively sub-let) to a guy who has been using the front parking space (common land with other tenants) as a storage site for his 3 cars and for another 2-3 parked off-street after hours. He cleans the cars and polishes them and prepares them for sale on the site and puts them up for sale on the road. The council has known about this for 4 years and has condoned this action, with full knowledge and approval from the leaseholder who has rented the property to this car dealer. Both the council and the leaseholder (who used to be an ex-employee of the council) are reluctant to do anything about this illicit trade. The leaseholder gets a tidy rent from the let. Residents have complained, but the council says it has no strong evidence for the claim. What is the best course of action?
