Police Federation

Principal Officers

We have eight principal officers as part of our National Board. The National Chair is elected by members, with candidates coming from the National Board and National Council, the National Secretary is selected from the National Board via an interview process, and all other roles are elected from among the National Board.

Simon Kempton

Simon Kempton

National Treasurer


Simon joined Dorset Police in 2000 working as a frontline response officer, both as a constable and as a sergeant, where he gained qualifications as a licensed search team leader and a hostage and crisis negotiator.

He has also worked in some more covert roles, including undercover policing, surveillance and counter-terrorist policing. This breadth of experience has given him the opportunity to build a well-rounded career with experience across a range of disciplines. Some of the roles have been subject to enhanced vetting, requiring the upmost levels of integrity and personal ethics.

Having become a Federation representative in 2009, Simon trained as a misconduct, equality and health and safety rep, and still maintains a role on his home board as a misconduct rep. This, alongside his occasional operational work, has enabled him to maintain links with operational colleagues.

After becoming a National Board member, Simon was elected as deputy national treasurer in 2017 to support the national treasurer and finance director by helping to implement the initiatives being brought forward, and building close working relationships with stakeholders. He was elected as national treasurer in 2019.

Throughout this period of time he was predominantly a frontline police officer on 24/7 response and neighbourhood policing.

After becoming a local Fed rep at Darlington, Kevin was elected as the constables' chair, recognising his leadership skills and diplomacy in discussions between the different rank Boards and in 2010, he was elected as the Durham JBB chair and branch conduct lead, becoming the youngest chair in the country at that time. Kevin became the Durham branch secretary and treasurer during 2013, holding both these roles until this June 2022, having been a member of the National Council throughout that time.

Kevin has attained all the PFEW, SFJ Level 4 Awards: in representing his members, in health & safety, in equality and for conduct & performance and attendance matters.

His priorities in his new role are to understand he is one of the next guardians of the national PFEW funds, ensuring PFEW has good financial governance, greater transparency and trust with its members and that PFEW funds are bringing the best possible value they can, as well as professionally building a healthy and stable financial future in order to allow PFEW to be able to continue to represent its members and police officers for many decades to come.


Craig Hewitt

Craig Hewitt

Head of Civil Claims

Craig has been a constable with Lincolnshire Police since August 2000. Before joining, Craig worked in the hospitality and financial sectors. He joined the police to try to make a difference in society.

Craig was a response and patrol officer in his home force for 15 years, joining the Federation as a workplace representative in 2009, before becoming the full-time secretary and treasurer of Lincolnshire Police Federation in 2015. Craig chose to become a rep after he was involved in a number of investigations and saw the valuable work done by the reps who looked after him; it made him want to help officers in similar situations.

During his time as a Federation rep, Craig has represented officers in equality matters, fairness at work issues, unsatisfactory performance procedures (UPP), unsatisfactory attendance procedures (UAP), ill health retirement, police regulation issues, post incident procedures (PIP), and many other areas.

As secretary of the Lincolnshire branch, Craig led on the introduction of a fit-for-purpose limited duties policy within his force and brought about adjustments to Lincolnshire's acting allowance, temporary salary and temporary promotion processes to ensure officers were paid correctly.

Craig became a National Board member in 2016, and sits on the professional development and operational policing business areas. He was elected as head of civil claims in 2018.
