Rock and roll legend Chuck Berry has died aged 90 in the US.
The singer was found unresponsive.
Berry's seven‑decade career boasted a string of hits, including classics Roll Over Beethoven and Johnny B. Goode.
He received a lifetime achievement Grammy in 1984 and was among the first inductees to the Rock and Roll Hall of Fame in 1986.
Singer‑songwriter Huey Lewis described him as "maybe the most important figure in all of rock and roll".
