Chesterfield looks to join up with Sheffield
Chesterfield Borough Council wants to join Sheffield City Region, which is a 'combined authority' made up of Rotherham, Sheffield, Barnsley and Doncaster.
This is a big decision which affects the whole of Derbyshire and if it happens, there's no easy way back.
It could mean the end of Derbyshire as an administrative county.
If the plans go ahead some key services in Chesterfield − the biggest town in Derbyshire − would be controlled by the combined authority and a powerful Sheffield City Region Mayor to be elected in May next year.
The Mayor and combined authority would take over responsibility from Derbyshire County Council for services in Chesterfield including major roads, funding for maintenance and road safety on all roads in the borough, public transport, travel concessions (Gold Card and b_line), skills for employment and major planning and investment projects.
The county council has always said it wants to work alongside Sheffield City Region as a good neighbour. But it does not want to be part of the combined authority because it does not believe this would be in the best interests of Derbyshire residents.
In November 2016 Derbyshire County Council took Sheffield City Region Combined Authority to the High Court because it believed a public consultation on whether the region should expand to include Chesterfield was unfair and misleading. The High Court ruled that Sheffield City Region's consultation was unlawful because it did not ask the direct question whether local people wanted Sheffield City Region to expand to include Chesterfield.
