Deletion of Borough of Middlesbrough

Comment: ec) The place has a complex and shifting history, detailed in ''https://www.bbc.co.uk/news/uk-england-tees-48024370 We Are Middlesbrough: Where and what is it?'' which includes the Middlesbrough Municipal Borough and Middlesbrough County Borough.  It concludes "''in answer to the question "where is Middlesbrough?": Middlesbrough is in the council borough of Middlesbrough, the ceremonial county of North Yorkshire and the Tees Valley authority area.  And that's about as clear as we can make it.''"  So explaining properly this may require lots of blue links just as we have London, City of London, Greater London, Greater London Council and many more.  Deletion is not helpful in this, per our policy
