A body was found off the cliffs of Beachy Head on Sunday morning (November 3) after an abandoned car was discovered on Saturday afternoon (November 2).
The RNLI Eastbourne lifeboat was launched, but on initial search of the area where the car was discovered, did not find anyone.
A spokesman for the Eastbourne lifeboat said the casualty was spotted the next day and was pronounced dead.
A spokesman for the RNLI said: “Initially the inshore lifeboat was requested to launch by Dover Coastguard to assist with the recovery of a body from the beach below Beachy Head cliffs.
“An abandoned car was discovered at the famous beauty spot yesterday (Saturday) afternoon and despite a thorough search of the area by the cliff rescue team no one was found.
“The casualty was eventually spotted from the cliff top early this morning (Sunday).”
The spokesman said the incident was not connected with the tragic loss of Newhaven boy Dylan Alkins last week.
Crews are still searching the area after the teenager was swept out to sea while playing at Newhaven’s West Beach on Sunday October 27.
The search for Dylan continued last week, including a sweep of the coastline from Beachy Head to Peacehaven by a police helicopter.
Last week Dylan’s dad paid tribute to his son who was an ‘amazing boy’ and a ‘cheeky’ and ‘lovable’ young man.
His mum Amy Kattenhorn added: “I will hold on to Dylan forever in my heart.
“I have the best and amazing memories of him that nobody can ever take away from me.”
