A large chunk of Britain’s Jurassic Coast has been lost following another massive rockfall.

A huge crack in the top of the 600ft cliff at Seatown, Dorset, had opened up following a landslip there in 2021.

Experts said it was only a matter of time before the rest of the unstable cliff would go and this has now come to pass.

Thousands of tons of mud and rock has slumped from the sandstone cliff onto the beach, blocking it off to the public.

It has taken a 2,000ft-wide section out of the 180 million-year-old cliffs.

It is also perilously close to the South West Coast Path which is walked by hundreds of people a day.
