This year's Grammy Awards ceremony honouring top performances in music has been postponed indefinitely because of the rapid spread of the Omicron variant of the coronavirus, organisers said on Wednesday.

The show had been scheduled to take place at an arena in downtown Los Angeles and broadcast live on the CBS network on January 31.

"Given the uncertainty surrounding the Omicron variant, holding the show on January 31 simply contains too many risks," CBS and the Recording Academy said in a joint statement, adding that a new date would be announced soon.
