• The parishes of Aintree, Ince Blundell, Maghull, Melling, Netherton, Sefton and Thornton became part of the Metropolitan Borough of Sefton in Merseyside.
• The parish of Simonswood became part of the Metropolitan Borough of Knowsley in Merseyside.
• The remainder of the former rural district became part of the new district of West Lancashire in Lancashire.
