It's one of the biggest issues in two key election battlegrounds - and parties are vying to convince voters their approach to pylons is the best.

But campaigners have warned East Anglia “will revolt” after Labour leader Sir Keir Starmer’s comments about energy infrastructure.

National Grid says the line, with 50-metre high pylons, is needed to carry electricity generated by North Sea wind farms.

Critics argue the power company has not properly considered alternatives, such as undersea cables.

Those critics were angered by Labour leader Sir Keir when, BBC presenter Nick Robinson asked if he would stand firm against people objecting to pylons in order to “get the economy moving” and if he was prepared to make enemies.

Sir Keir said: “Yes, we’re going to have to be tough. We’re going to have to change how things get done.”

His comments triggered an angry response from campaign group Essex Suffolk Norfolk Pylons said: “It is disgusting to hear a possible future prime minister talking in such arrogant and dismissive terms about his electorate.

“Taking tough decisions is not the same as vowing to make enemies of the people.

“If Sir Keir wants a fight if Labour wins the election, he’s got one coming. The people of East Anglia will revolt.”

The Labour leader’s comments come at a time when pylons are looming large over the election campaign.

The Conservative Party manifesto included a commitment for a "rapid review into the advantages of alternative network technologies, compared to overhead pylons".

It stated: "The review will consider moving to a presumption in favour of undergrounding where cost competitive."

But the Green Party, which has made the Waveney Valley a target seat, said the Tory manifesto is not a commitment to an offshore solution.

The Greens said their manifesto states: "We support the extensive use of offshore power distribution networks to reduce the amount of onshore connection infrastructure needed along our coastlines, an approach being applied by our European neighbours."

Adrian Ramsay, Green candidate for Waveney Valley, said: "I'm delighted our manifesto has a commitment to offshoring to reduce the impact of pylons and onshore infrastructure.

"The Conservative manifesto appears to have rejected the offshoring option and is only talking about undergrounding if it is cheaper than pylons.

"When it comes to reaching net zero, it is more important to get it right than trying to do it on the cheap."

Dr Catherine Rowett, Green candidate for South Norfolk, said: "Laying cables underground is still hugely destructive to hedges, trees and rare habitats, along a route that is sparsely populated—which is precisely why it is a haven of precious wildlife and biodiversity."

The Liberal Democrat manifesto includes a commitment to build more “energy interconnectors” which would be “located carefully to avoid disruption to local communities and minimise environmental damage”.
