Nothing new there. Time and again when they mention the new Rolls Royce enterprise park,that is clearly situated within the borough of Rotherham at Catcliffe, do the news teams say it's in Sheffield. No it ferkin isn't.
Neither is Boundary Mill on the adverts saying it's in Sheffield when it's on the Catcliffe retail park with Morrisons.
As for the Robin Hood airport, biggest farce ever. How can it possibly be called Doncaster /Sheffield Robin Hood airport? It's even on the outskirts of Doncaster heading outwards so where does Sheffield even come into it?
