Wendy Williams, the lead inspector, said: “As long as the criminal justice system does not operate effectively and efficiently, there will be a risk that perpetrators will not be brought to justice.” 

The inspectorate proposed specialist rape courts to help speed up justice and reduce the backlogs of sexual assault cases, as well as providing a “testbed” for a more sensitive approach to victims.

Andy Cayley, the chief inspector of the CPS, said that the use of pre-recorded video evidence by victims – which Dominic Raab wants extended nationwide – already saw judges supervise and agree a line of questioning with prosecutors. 

“You don’t need to be aggressive and intimidating to get the truth out of somebody,” he added.

A government source said that the Justice Secretary “liked” the idea of specialist rape courts, adding: “He has commissioned research on how it could be delivered.”

Deputy Prime Minister, Lord Chancellor and Secretary of State for Justice, Dominic Raab said: “This is a sobering and considered analysis. We accept the findings, and will look at how best to address them in the most rigorous and effective way possible.

“The Government is absolutely determined to give victims greater support and swifter justice – and ensure they see their attackers punished.” 

Max Hill QC, Director of Public Prosecutions said: “We know victims of sexual offences can suffer lasting trauma, and too often their experience of the criminal justice system adds to their suffering. The CPS is committed to making the changes needed so that more victims see justice.

 “Strong collaboration between prosecutors and police is vital, and we have a strong joint commitment to improve how we work together so that we can drive up the number of rape cases we bring to court.

 “We are undertaking extensive work to bring about urgent change, and to improve the support given to victims – working with support services we will improve communication and better understand how we can help victims through the legal system so they can give their best evidence. We accept the findings of this report and will make sure we are providing the compassionate, consistent care that victims rightly deserve.”
