Railway bottlenecks holding back better train services in Norfolk and Suffolk must be made priorities for improvement by the Labour government, the region's MPs have demanded.

MPs have written to transport secretary Louise Haigh urging that she put revamps for Ely and Haughley junctions at the top of the government's to-do list.

Members of the East of England All-Party Parliamentary Group say the long-sought improvements at the key rail junctions would unlock economic growth and bring better services for passengers.

The upgrades for Ely North junction and Haughley junction, near Stowmarket, were announced by then prime minister Rishi Sunak almost a year ago.

MPs say the upgrades would unlock thousands of extra freight trains from the port at Felixstowe, while also increasing frequency of passenger services.

It comes as two transport bodies, England’s Economic Heartland and Transport East, released an updated report on the benefits of improvements.

The report states Network Rail's proposed changes would cut road congestion, double passenger services on the Ely to King’s Lynn line and return £4.89 of economic benefits for every £1 invested.

Labour's Jess Asato, MP for Lowestoft and co-chair of the East of England All-Party Parliamentary Group, said: "The upgrading of Ely and Haughley junctions will benefit people and businesses right across East Anglia – including Lowestoft, the most easterly town and base for our essential off-shore energy industry.

"These projects must be funded as a priority."

Jerome Mayhew, Conservative MP for Broadland and Fakenham, said the upgrade of Ely was "essential".

He added: "It will also unlock additional passenger services between Norwich and Cambridge, fuelling the Norwich to Cambridge tech corridor."
