A fresh protest is to be held over controversial plans for 50-metre tall pylons over miles of Norfolk and Suffolk countryside.
Councillors, MPs and concerned campaigners are to take part in the protest on the border of the two counties.
The action aims to build on the joint letter leaders of Norfolk, Suffolk and Essex county councils wrote to National Grid, urging a rethink over the Norwich to Tilbury power line project.
The power company is consulting over plans for the 112-mile line pylons, from Dunston, near Norwich to the south-east.
Campaigners say the towering structures would have a devastating impact on the countryside and communities - and that not enough has been done to explore alternative options, such as putting the cables offshore, under the sea.

To push their point, they will hold a protest at Wortham Ling, on the Norfolk/Suffolk border on Saturday, September 30.
Christine Murton, from Wortham Ling, is one of the campaigners.
She said: "The event promotes an offshore grid, or in the event that this is not feasible, undergrounding in sensitive areas along the route such as the Waveney Valley, as proposed by the three councils in their joint letter.
"Here at my home, the 50-metre pylons are proposed to go within 50 metres either side of a nature reserve and a site of special scientific interest."
Councillors likely to attend include Keith Kiddie, Norfolk county councillor for Diss, South Norfolk Council chairman James Easter and Richard Rout, deputy leader of Suffolk County Council.
National Grid said the scheme is needed to take power from wind farms off the Norfolk Coast to increase supply as demand increases, while an offshore grid would be costlier to energy bill-payers and have less capacity.

Campaigners are also waiting to see what impact prime minister Rishi Sunak's "comprehensive new reforms to energy infrastructure" will have on the project - if any.
Mr Sunak had said he intends to set out a spatial plan for energy infrastructure and to "speed up planning for the most nationally significant projects". Details have yet to be announced.
