No, a parish council coexists with a principal council, like Tower Hamlets Council, but it is not a replacement for it. The two would need to work together. The London Borough of Tower Hamlets wards of Spitalfields & Banglatown and Weavers would continue to exist. Local people would still elect ward councillors to represent them on the borough council. Tower Hamlets Council would still continue to provide most services to local people.
