Would it be possible to produce a table similar to this one: https://www.ons.gov.uk/economy/grossdomesticproductgdp/datasets/regionalgrossdomesticproductlocalauthorities, but with local authority districts defined as before the changes in April 2015?

Thank you for your request however we do not hold the information you have requested.
