More than 100 business leaders representing tens of thousands of workers have become the latest to back calls to locate the Treasury’s new northern economic campus in Teesside.

Figureheads from some of the area’s biggest employers – including PD Ports, Thirteen, Cleveland Cable Company, Charles Clinkard and Wilton Group and have signed a joint letter to Rishi Sunak, urging the chancellor to bring the jobs to the Tees region.

Government has proposed 750 senior Whitehall officials move out of the capital to a purpose built northern economic campus, dubbed ‘Treasury North'. The move has received cross party support from politicans across the Tees Valley.

And the independent letter, signed by 115 business leaders – calls on the government not to miss this “golden opportunity to give our region a much-needed and long overdue economic boost”.

“The Tees region has a range of perfect locations to benefit from the Treasury North,” it says.

“We have the first-class skills and a wide range of outstanding businesses to service a government department ready and waiting.

“Just as importantly, we have an economy that needs help from the levelling up process and would benefit hugely from the once-in-a-generation investment and positive spotlight from such a move."

The letter insists that by transferring Treasury jobs – and the related investment – from London to another city, such as Newcastle, Leeds or Manchester, would “not be levelling up at all”.

Karl Pemberton, president of the Institute of Directors Tees Valley and managing director of Active Financial Planners, said: “The Tees Valley has been dealt many blows in modern times, far more than most. However, I now believe that we should be at the front of queue when it comes to the government’s levelling up agenda.

“We have the locations and the workforce available, and we have the resilience to make the opportunity a huge success.

Jane Armitage, managing partner of Jacksons Law Firm, said: “The Tees Valley has an excellent workforce ready and willing to work in Treasury roles and excellent training providers to train the employees of the future.

“These people need to the opportunities that this move would create and they need to know the government shares our belief that this area has so much to offer.”
