Thames and Chiltern

The Crown Prosecution Service (CPS) prosecutes cases that have been investigated by the police and other investigative organisations in England and Wales.

Thames Chiltern mapCPS Thames and Chiltern is one of 14 CPS areas across the country and we are responsible for prosecuting cases in Bedfordshire, Hertfordshire, Berkshire, Buckinghamshire and Oxfordshire.

We work in partnership with our three regional police forces - Hertfordshire Constabulary, Bedfordshire Police and Thames Valley Police - the courts, the judiciary and other partners to deliver justice. However, we are independent, and make our decisions independently of the police and other agencies.

Chief Crown Prosecutor Jaswant Narwal is the head of CPS Thames and Chiltern, and she is supported on the legal side by Deputy Chief Crown Prosecutor Chris Derrick, who has responsibility for Crown Court cases, and Olivia Pearson, who has responsibility for magistrates' court cases. Rachel Mort is our Area Business Manager, who is responsible for business and operational delivery functions across our Area.

We have around 300 members of staff who are based in St Albans, Reading and Liverpool. Our workforce is made up of legal and operational delivery staff who all play a part in bringing criminal prosecutions to court. And we have an area business centre which includes specialist business support and administrative functions such as human resources, finance, communications and performance, all of which help to support the rest of the business.

Olivia Pearson, DCCP (magistrates' courts)

As Deputy Chief Crown Prosecutor for CPS Thames and Chiltern, Olivia is responsible for the Magistrates' Court performance across our Area.

She is also our local lead for domestic abuse, stalking and harassment, prisons, hate crime, football offences and youth justice.

Before joining us in 2019, Olivia worked for the Department of Work and Pensions as a senior advisory lawyer in the Data-sharing, Fraud and Decision-making team. Whilst at the Government Legal Department, she also spent time working on Brexit no deal planning at the Cabinet Office.

Rachel Mort - Area Business Manager

Rachel Morth, Area Business Manager

Rachel is our Area Business Manager and has responsibility for delivering the operational business across our Area.

As well as having oversight of all our business functions, Rachel is responsible for staff and financial management, performance monitoring and the implementation of all our operational business systems. Working alongside our chief crown prosecutor, Rachel’s role is to ensure the appropriate resources are in place for our Area team to operate effectively and efficiently.

Rachel began her career with the CPS in 2002; she joined us as an administrator and has held a variety of roles since then including case progression manager, branch manager, head of the Area operations centre, and business change and delivery manager. She took on her current role in 2016.

Our Magistrates’ Court Team prosecutes offences including assaults, domestic abuse, criminal damage, possession of drugs, minor public disorder, minor traffic offences (excluding those dealt with by the police as police-led prosecutions), and commercial burglary.

This is not an exhaustive list, but the team is generally responsible for offences where the maximum permitted sentence for each offence does not exceed six months' imprisonment, or one year if two or more relevant offences are to be considered.

The Crown Court Team deals with cases such as murder, robberies, serious assaults, dwelling house burglaries, complex fraud, the supply and trafficking of drugs, and the most serious road traffic offences.

The serious nature of these offences mean they have to be tried before a jury or heard at the Crown Court because the magistrates’ court do not have sufficient sentencing powers for these crimes.

Our Complex Casework Unit (CCU) deals with the most complex cases in our area. The team of experienced specialist lawyers, paralegal officers and operational delivery staff work in collaboration with our three police forces to tackle serious, organised and cross-border crime across Bedfordshire, Hertfordshire, Berkshire, Buckinghamshire, and Oxfordshire.

Offences dealt with by the CCU include human trafficking, large-scale drugs importation, cold case murders, serious fraud and money laundering.

Our dedicated Rape and Serious Sexual Offences (RASSO) Team deals with rape cases (including attempted rape), child sexual abuse cases, serious sexual offences and allegations of perverting the course of justice or wasting police time which arise from false accusations of rape and domestic violence.

All our lawyers who work on rape and serious sexual offences prosecutions are specialists who are highly trained in the complexities of these cases, and they will prosecute them whenever our legal test is met.

Working with You

We work with our local communities so that we have a better understanding of how crime affects them, and so that we can explain the role of the CPS and the work we do.

Through our local scrutiny involvement panel, members of the public and voluntary organisations bring a community perspective to our planning and decision-making, particularly on priority issues such as hate crime, domestic violence and sexual violence. Public sector partners, including our three local police forces, the courts and local councils, are also represented on the panel.

In addition, we hold community conversations with different community groups across our area; this is an ideal opportunity for us to hear first hand about people’s experiences of the criminal justice system and for us to explain our role within it.

If you would like further information about our local scrutiny involvement panel, or would like us to join your community group for a conversation, please contact Mandy Saxon, our Inclusion and Community and Engagement Manager, at

Victims and Witnesses

Victims and witnesses are vital in helping us bring offenders to justice. We understand being a victim or witness can be difficult, and we will support you through the prosecution process so that you can give your best evidence at court.

Our prosecutors work closely with our local witness care units which are staffed by police witness care officers who will be your single point of contact if you are a victim or witness. They will provide you with information, practical help and support throughout a case, from when a defendant is charged through to sentence.

Victim Liaison Unit

Our Victim Liaison Unit is responsible for ensuring that victims are informed about any decisions our prosecutors make to stop or to significantly change the charges in a case.

If our prosecutor has not been able to communicate with you directly at court about a decision, our Victim Liaison Unit will write to you providing a short summary of the reasons for the decision.

If you want further details or explanations about the decision you can contact the unit.
