Campaigners have called on King Charles to help them stop Britain's biggest solar farm set to spread across the Blenheim Estate where Sir Winston Churchill was born.

The £800million Botley West project is expected to cover almost 3,500 acres of land in Oxfordshire with solar panels.

This includes 2,000 acres of the Blenheim Estate, which the Duke of Marlborough's half-brother Lord Edward Spencer-Churchill, who runs the property, has agreed to lease.

Locals branded the plans an outrage and Tim Summer has written a letter to the King citing an act from the early 18th century to explain that he must intervene.

He claimed that the Blenheim Estate does not officially own the land, explaining that it is leased by the Crown to the Duke of Marlborough.
