The Government needs to invest more in building up skills and industry in the so-called 'northern powerhouse' cities, according to a report.
The Centre for Cities think-tank says Leeds and Sheffield are 'underperforming' in economic terms - by around 40 per cent - in comparison with their European counterparts.
The report says simply building better transport links between our northern cities, such as HS3, is not enough.
The Government responded that its agenda is already much broader than simply focussing on transport.
