Devolving powers over employment, taxes, skills and transport to north Wales would boost its economy, jobs and productivity, a report backed by the region's six local councils says.

Billed as a "growth vision", it aims to create at least 120,000 jobs by 2035.

The document, also supported by business leaders and colleges, aims to boost the value of the local economy from £12.8bn in 2015 to £20bn by 2035.

The plans are in line with those for a Northern Powerhouse in England.

Those proposals, from the UK government, involve creating directly-elected mayors.

The north Wales plans were backed by the region's six council leaders and chief executives over the summer.

Prepared by the umbrella body the the report describes the area as being "well placed" to acquire powers from UK and Welsh ministers.

After formal approval by council cabinets, negotiations will begin with the UK and Welsh governments for new responsibilities and extra funding, including a possible "Growth Deal" for north Wales.

Boosting the energy and manufacturing sectors are at the heart of the proposals, with a planned new nuclear power station at Wylfa, on Anglesey, being central.

, Gwynedd's cabinet member for the economy Mandy Williams-Davies said: "If funding is secured to deliver the action plan of projects, the region will experience sustainable economic growth and the value of the north Wales economy from £12.8bn in 2015 to £20bn by 2035.

"Such growth rate will generate at least an additional 120,000 new employment opportunities."

Council leaders hope to secure a deal similar to the £1.2bn Cardiff Capital Region agreement approved in March.
