Eight policemen who are now retired colluded to send five innocent men to jail for the brutal murder of a Cardiff prostitute, a jury has been told.

Lynette White was killed in 1988 in a flat in the docks area of Cardiff.

The officers all deny conspiracy to pervert the course of justice and two other people deny perjury.

It is believed to be the biggest trial of police officers in British legal history.
