Northern leaders want tens of billions of pounds for transport projects to boost the region.
They called for a “Northern budget” to pump cash into road and rail schemes to revitalise the area after decades of under-funding.
Demands include £7billion for a “Northern Infrastructure Pipeline” – a list of shovel-ready projects to be delivered by the mid-2020s; a commitment to build the full £39billion Northern Powerhouse Rail (NPR) network by 2040 and £1billion for Transport for the North (TfN) over the next three years.
The body’s chief executive Barry White said: “The North is now at the top of the national political agenda, with promises to balance out the UK’s economy and unleash our potential by better connecting our towns and cities.
“We now need a Northern Budget to make both the shovel-ready projects and the ambitious longer-term programmes like Northern Powerhouse Rail a reality.
“Closing the productivity gap between North and South is essential if we’re to compete on a global stage – but the North’s constrained by creaking infrastructure.
“These are the minimum requirements needed to overturn the under-investment, under different Governments, stretching back decades.”
Liverpool City Region metro mayor Steve Rotheram called for a transport shake-up which benefits the whole region.
The former MP said: “Northern Powerhouse Rail is vital to the North’s future economic success, supporting 850,000 new jobs by 2050 and an extra £100billion into the economy.
“The North is clear that we only support NPR proposals that deliver the whole network, from Liverpool to Hull, along with HS2.”
However, Northern Powerhouse Partnership Director Henri Murison blasted the shopping list for lacking ambition.
“I’m concerned that the Northern Budget Transport for the North are calling for does not go nearly far enough for long-suffering Northern commuters and passengers,” he warned.
“It is not as far as the £120billion Northern Powerhouse MPs and peers have called for by 2050.
“Improving transport across the North – including the new Northern Powerhouse Rail line between Leeds and Manchester through Bradford city centre and its wider network – is vitally important.
“However, as the National Infrastructure Assessment recommended, within the target of 1.2% of GDP spend on infrastructure, the UK can also afford both HS2 and better transport within city regions like North East, Leeds and Bradford with their neighbouring towns.
“There seems to be little or no reference to this in TfN’s priorities.”
In his first speech after moving into No10, Boris Johnson insisted he wanted “to be the PM who does with Northern Powerhouse Rail what we did with Crossrail in London”.
Speaking in Manchester, the ex-London mayor said: “I am going to deliver on my commitment to that vision with a pledge to fund the Leeds to Manchester route.
“It will be up to local people and us to come to an agreement on the exact proposal they want – but I have tasked officials to accelerate their work on these plans so that we are ready to do a deal in the autumn.”
