Rishi Sunak plans to restrict the installation of solar panels on swathes of English farmland, which climate campaigners say will raise bills and put the UK’s energy security at risk.

Last year, then prime minister Liz Truss attempted to block solar from most of the country’s farmland. The plans were deeply controversial and unpopular, and were dropped when she left office.

However, solar panels in the countryside are disliked by many rural Conservative MPs, and the Observer can reveal that Sunak and environment secretary Thérèse Coffey have revived plans to put new restrictions on this form of cheap renewable energy.
