The role of the PCC is to be the voice of the people and hold the police to account. PCCs are responsible for the totality of policing.
They aim to cut crime and deliver an effective and efficient police service within their force area.
PCCs have been elected by the public to hold Chief Constables and the force to account, effectively making the police answerable to the communities they serve.
The new Commissioner will take up the role officially on May 13, and will serve a three-year term until 2024 due to the year-long postponement as a result of Covid-19.
