People are being urged to stay away from cliff edges after two "significant" collapses in the space of a few weeks.

Councils across East Sussex have said that the cliff edges are "unstable" and that "huge sections" were reported to have fallen last month.

A warning has now been issued and a joint campaign has been set up in time for the Easter school holidays.

The campaign, supported by agencies including HM Coastguard, South Downs National Park Authority and councils, is aimed at raising awareness of cliff dangers.

A spokesman for Eastbourne Borough Council said: "Cliff erosion is a natural process and part of the evolution of the coastline and as well as the risk to those walking on top of cliffs, it can also present dangers to those on the beach below.

"Sadly, we continue to see people getting perilously close to the edge of the cliffs to take a selfie, or walking along the base of the cliffs without appreciating the danger they are putting themselves in.

"The cliffs contain many overhangs and cracks that visitors may not be able to see and the unstable chalk can fall at any time with absolutely no warning.

"We understand why visitors to come to East Sussex to enjoy the spectacular coastline and we want to encourage people to continue to visit the area safely."

People are also reminded to check tide times when walking along the coast beneath the cliffs to make sure they do not get trapped.

One of the latest cliff falls was in Newhaven earlier this month.

People were reminded to take care when walking along the cliff tops and to "keep children and pets close when visiting the coast."

A spokesman for Lewes District Council said at the time: "Following recent cliff falls in Newhaven, Peacehaven and Seaford, we are reminding all residents and visitors to stay well clear of cliff edges and bases."

In emergencies people should dial 999 immediately.
