The figures which show that people in the North are still being short-changed by the government

The government’s commitment to rebalancing the economy has been called into question, with new research showing that planned infrastructure investment is “heavily biased” towards London.

Analysis of national infrastructure projects by researchers at the Sheffield Political Economy Research Institute (Speri) suggests that George Osborne is “failing to deliver” on his Northern Powerhouse promises.

The study describes how London is set to receive more funding from the public purse than every other English region combined.

How projects in the North and South compare

The £208m Transpennine Electrification to improve routes in Yorkshire and the Humber was delayed indefinitely in June and its future is in doubt.

Other projects in the North include a £14m redevelopment of Newcastle’s city airport’s departure lounge, small in cost compared to the £497m Gatwick Capital Investment Programme.

In Yorkshire and the Humber a £535m project to improve power distribution is under way, small compared to a £4.2bn “supersewer” for London.
