Dave Prowse, who played Darth Vader in the original Star Wars trilogy, is calling time on public appearances.

on the 82-year-old's social media accounts said he would "no longer be doing any personal appearances or conventions due to health problems" from January 2018 onwards.

Prowse was the man behind Vader's mask in Star Wars, The Empire Strikes Back and Return of the Jedi.

He also played the Green Cross Code man in television road safety commercials.

Born in Bristol in 1935, Prowse was a successful bodybuilder and weightlifter before landing his iconic Star Wars role.

His face was never seen in the films though, while his voice was dubbed by US actor James Earl Jones.

When Vader's mask was removed in Return of the Jedi, another actor - Sebastian Shaw - was revealed beneath.

Two new actors - Daniel Naprous and Spencer Wilding - shared the role of Vader during his brief appearance in last year's Rogue One: A Star Wars Story.

Prowse, a fixture on the convention circuit since Jedi's release in 1983, announced last year "" that he would no longer attend international events.

In 2014 he had dementia, though this did not prevent him participating in the 2015 documentary I Am Your Father, or recently for singer Jayce Lewis.
