The South Downs National Park Authority, which is ‘responsible for keeping the South Downs a special place’, has warned people to beware of the ‘precarious’ section of the cliff.

He said people should stay away from the area due to the unpredictable nature of cliff erosion.

It said: ‘We would always advise people to stay away from the edges and bases of cliffs. Given the nature of chalk, cliff falls occur randomly as part of natural coastal erosion processes.

“Cliff Safety messages continue to be shared through our communication channels, local signage and on-the-ground engagement with the public.”

Trevor Beattie, chief executive of the South Downs National Park Authority, said the cracks were a demonstration of climate change.
