The coalition government has reaffirmed its commitment to developing the UK's energy and transport infrastructure following the news that a host of new projects have passed the first barrier to government funding.

Schemes worth a total of £33 billion are now at the stage known as prequalification, meaning that they are eligible for the UK Guarantee scheme, explained treasury chief secretary Danny Alexander.

While they will not all receive funding, this nevertheless represents a significant step in the development of British transport links and energy hubs.

Notable projects include a major extension to the Northern Line, taking it to Battersea, and the construction of the Mersey Gateway.

"Getting our infrastructure right means we can be globally competitive, boost growth and create jobs across the UK," said Mt Alexander.

The Mersey Gateway will link up Runcorn and Widnes, easing congestion on the Silver Jubilee Bridge and creating jobs and investment in the region.
