Campaigners battling to stop miles of pylons being built across swathes of Norfolk and Suffolk countryside have written to King Charles III to ask for help in their fight.

The Essex Suffolk Norfolk Pylons action group has taken the "unusual step" of writing to the recently-crowned monarch as part of their efforts to secure a rethink over National Grid's East Anglia GREEN project.

The plan for the line of 50 metre tall pylons, which would stretch for 110 miles through Norfolk, Suffolk and Essex, has sparked criticism.

National Grid says the pylon route is needed to transport wind energy generated off the Norfolk coast.

But critics, including the action group and MPs such as South Norfolk's Richard Bacon and former home secretary Priti Patel, MP for Witham in Essex, have campaigned for the line to be buried under the sea.

And Martin Snook, from the Essex Suffolk Norfolk Pylons action group, has written to the king appealing for him to help trigger a rethink.

He said: "We decided to contact King Charles at this point because we believe that, as head of state, he should be aware of what is going on before it is too late to change course.

"The National Grid pylons proposal is a bad solution that will leave an awful legacy.

"Our letter is possibly an unusual step to take but the more time passes the greater the risk the project will proceed in its current form by default."

Rosie Pearson, founder of the action group, said: "Everyone knows how committed the king is to environment conservation, so we hope he will be able to help us in some way.

"We are aware he doesn’t intervene in political disputes but he may be able to help persuade the government to consider the offshore alternative we as a group have researched and costed."
