Fans of Ahmet Kaya have hit social media urging the soulful Brit to credit him on her new song Million Years Ago, claiming the song features phrases and melody from his 1985 song Acilara Tutunmak.

But Adele has a big supporter on her side - Kaya's widow Gulten tells Turkey's Posta newspaper she doesn't believe the singer stole her late husband's song, but added, "However, if she consciously did it, then it would be theft."

Kaya died in exile in Paris, France in 2000.
