A teenager's been jailed for a minimum of 14 years for murdering his ex-girlfriend for a dare.

Joshua Davies was 15 when he bludgeoned Rebecca Aylward to death with a rock the size of a rugby ball near Bridgend in Wales, last October.

Swansea Crown Court heard he used to speak openly about how he'd kill her, and
that a friend joked he'd buy him breakfast if he actually did it.
