Controversial charging decisions in the cases of Lord Janner, Operation Elveden and a doctor accused of female genital mutilation have brought a hostile reaction in the media to the Director of Public Prosecutions and increasing concern about the health of her organisation - the Crown Prosecution Service.

Over the past five years the CPS has seen budget cuts of over 25% resulting in job losses and internal reforms. Despite this, the organisation maintains that it continues to improve performance - measured by conviction rates in both magistrates' and Crown Courts.

However, there are increasing concerns about staff morale, the quality of decision-making and the standard of advocacy in court . BBC Home Affairs Correspondent, Danny Shaw has been hearing frank testimony from both inside and outside the CPS which presents a revealing picture of the justice system in England and Wales.
