25 August 2013 Last updated at 10:54 BST
Former top Chinese politician Bo Xilai has accused his ex-police chief of lying over allegations of abuse of power.
Mr Bo launched a scathing attack on Wang Lijun, his former associate in the central city of Chongqing, on the fourth day of Mr Bo's trial.
Many analysts assume the outcome of the trial has been predetermined with a guilty verdict, however, observers say Mr Bo has put up a spirited defence.
