Regional mayors have met at the Mayoral Council in York, as more powers are moved out of Westminster.
Under the Right to Request scheme, mayors will have more powers to shape local services, from protecting homes against flooding to supporting young children with special educational needs.
Bespoke agreements cover a new approach to youth justice in Greater Manchester, the government supporting the Mayor to use tech to transform public services in Liverpool City Region and reshaping arts funding in the North East to ensure more money is spent on local priorities.
Under the Right to Request scheme, mayors can formally request new controls, funding and partnerships from government. The government is legally required to respond within six months.
Communities Secretary Steve Reed said: "This government is serious about shifting power out of Westminster and into the hands of our mayors.
"These agreements mean real change for communities across the country with more local decision-making, better services and a stronger voice for people who know their areas best. That’s what devolution is all about."
