Meredith Kercher murder: Retrial explained in 60 seconds

A court in Italy will on Thursday announce new appeal verdicts for US citizen Amanda Knox and her former boyfriend, the Italian Raffaele Sollecito, who were both accused of murdering British student Meredith Kercher in 2007.

They were acquitted of the crime on appeal in 2011, after four years in custody, but that ruling was dismissed as flawed last year by Italy's supreme court, and a new appeal ordered.

Both maintain their innocence.

Here is the background to the case - explained in 60 seconds.
