Huw Watkins pens carol for Kings College, Cambridge concert

It is one of the biggest events of the festive calendar - the concert held by the choir of Kings College, Cambridge.

Broadcast on TV and radio, it reaches people around the world.

Work by a Welsh composer will be performed alongside more traditional carols.

Huw Watkins has written a two minute carol - the words in Welsh - which will join the service of Nine Lessons and Carols on Christmas Eve.
