A £15 billion plan to improve road and rail connections in the North of England is to be unveiled by five of the region's cities.

The joint One North report, which has been developed by Leeds, Liverpool, Manchester, Newcastle and Sheffield, will include plans for a new 125mph inter-city rail link, faster links and better access to ports and airports.

The report will be presented to George Osborne after he said that faster links could create a 'northern global powerhouse'.

Osborne said the plan for a high-speed rail link between Manchester and Leeds could cost up to £7 billion - but could be cheaper if existing rail lines were updated.

Shadow Treasury minister Shabana Mahmood said: "We welcome this report and the city regions of the North of England working together to strategically plan to deliver the growth and jobs we need.

"But only Labour will properly back our city and county regions with ambitious plans to devolve more funding and economic power to them."
