LABOUR warned today that the government will not be forgiven if it fails to secure the future of a huge potash mine planned for the north-east of England.

The project to build the mine in Teesside has been thrown into jeopardy after the company behind the project, Sirius Minerals, cancelled plans today to raise £403 million to secure its future.

Sirius said “market conditions” — including uncertainty over Brexit and lack of government support — had created instability for the mine’s future.
