The King's new Coast Path is under threat from a major new development just weeks after its grand unveiling.
A fierce row has erupted over proposals to build 30 homes on a field next to the spot where King Charles III inaugurated the England Coast Path at the famous Seven Sisters cliffs in East Sussex.
Lewes District Council has put forward plans for up to 30 affordable homes on Chyngton Field, a 2.7-hectare site on the outskirts of Seaford.
The authority has classified the land as suitable for development.
However, the proposal has sparked fierce opposition from local residents, conservation groups and walkers who fear it will damage an area of outstanding natural beauty.
The field sits just beyond a ridge from the Cuckmere coastguard cottages, an iconic row of buildings with views across the Seven Sisters that has become one of the most photographed locations in Britain.
King Charles chose this stretch of coastline as the setting to launch the 2,700-mile coastal trail, which holds the distinction of being the world's longest.
Just a fortnight ago, more than 200 demonstrators encircled the field to voice their opposition.

Protesters argued that new housing should be built on brownfield sites rather than untouched areas rich in biodiversity.
Rupert Kirby, one of those opposing the scheme, told The Times: "Developing this site would erode the natural character of a nationally significant landscape, set a worrying precedent for future encroachment into protected areas, impact the setting and integrity of the neighbouring SSSI and undermine the very reason people are drawn to this area in the first place.
"This isn't about opposing development in principle it's about putting it in the right place."
The National Trust, Sussex Wildlife Trust and Seaford town council have all formally objected to the proposals.

|A spokesman for the National Trust said: "The natural environment is one of the district's greatest assets.
"We would like to see the setting of the South Downs National Park conserved and protected especially its landscape qualities, wildlife and its dark skies and we believe this applies to Chyngton Field."
The South Downs National Park Authority has identified it as a nature-friendly action area intended to support wildlife conservation efforts.
A petition demanding the council reconsider its plans has attracted more than 3,000 signatures.
