The National Health Service (Determination of Districts) (No. 4) Order 1992
This Order abolishes the district of Airedale and varies the district of Bradford so as to incorporate part of the former district of Airedale. It also abolishes the districts of Harrogate, Northallerton, Scarborough and York and merges those districts, together with the remainder of the former district of Airedale, into a new district called North Yorkshire District (article 2 and Schedule).
