Sir Cliff Richard has told fans he's OK and back to his best after a year in which he's been wrongly accused of sexual abuse and seen his sister pass away after

The Christian singer has made his first public appearance since his sister Donna Goulden died.

He greeted more than 1,000 fans outside his vineyard in the Algarve.

According to the Daily Mirror, he said: "I'm OK, everything will be OK. I want to thank all my fans for being so amazing, they have been incredible."

He went on to tell them: "I'm back to my best."

Throughout 2016 he's been subject to a police investigation looking into accusations that he sexually assaulted a teenage boy at a Billy Graham rally in the 1980s.

The case was dropped back in June on grounds of insufficient evidence.

He spoke with fans at an event to launch a new wine at the Adega do Cantor vineyard in Albufeira.

His other sister, Joan, 66, joined him at the occasion.

She told the paper: "It's been really horrible. But today shows how many fans he's got. They stick by him no matter what.

"I always say that to him, 'They stick by you'. They've always believed in him which is so great. He is so lovely and such a wonderful person."
