Why are there no addresses listed for the English County of Middlesex?
Many of the old English Counties were abolished in the Government re-organisation of 1963 and Middlesex was among these. Addresses in Middlesex were absorbed into a number of the surrounding counties, including Hertfordshire, Essex, Berkshire, Surrey and Greater London. Despite the fact that more than a quarter of a century has passed since the reorganisation, the Postal Authorities have yet to catch up with all of these changes!
