Cumbria's Police and Crime Commissioner has decided not to stand for re-election in May 2016.
Richard Rhodes said in a statement that he was making the decision "with mixed feelings".
The county's first PCC has been involved in schemes designed to help the victims of crime, including providing domestic and sexual assault advisors at hospitals.
He's also led restorative justice schemes.
In 2013 he was embroiled in controversy when details of him hiring a chauffeur driven Mercedes, costing £700, were leaked.
It was a huge privilege and honour for me to be elected to serve as the first Police and Crime Commissioner for Cumbria in November 2012.
