Residents have voted for a Yorkshire-wide regional assembly as their preferred model of devolution.
The call came from the UK’s first Citizens Assembly, which concluded in Sheffield at the weekend.
Residents chosen from across the county to take part said politicians should engage with Government for a more ambitious deal after debating with local and national experts on how the region should be governed.
Currently, Sheffield City Region has an in-principle £900m deal which would create a directly elected mayor for the region.
Other assembly votes showed strong opposition to the mayor and to the current proposed deal.
Professor Matt Flinders from Sheffield University, who was the project’s principal investigator, said: “What they want is genuine devolution with more powers and stronger accountability.”
