Martyn Underhill was re-elected as PCC for Dorset in 2016.
At a national level, Martyn is a member of the National Police Chiefs Council Audit and Assurance Board, and is the national lead for PCCs on Brexit, Custody and use of force issues. Since 2014, he has been the Chair of the Independent Custody Visiting Association.
He is also a trustee or chair of a number of charitable organisations and trusts, including The Police Scholarship Trust and Safewise. Of the UK Police Memorial Trust, he says:
“I am honoured to be a trustee of the UK Police Memorial Trust. Every day our brave police officers put themselves in harm’s way to protect our communities and to keep us all safe. The memorial will be in recognition of the many sacrifices made in the line of duty and will be a fitting tribute to ensure that they are never forgotten.”
