After five years in charge, Julie Spence has today announced her retirement as chief constable of Cambridgeshire Constabulary.
She will step down from her post leading the force on September 5.
Mrs Spence said: "It has been an extraordinary privilege to lead Cambridgeshire Constabulary over the past five years on a journey to improve the service we give to the people of Cambridgeshire.
"It has without doubt been the highlight of my 32 year career and I believe the county now has a force it can be proud of.
"I feel the time is right to hand over the reins to someone else to guide the force through the next part of the journey.
"By announcing my retirement now, the Police Authority has six months to find the right person to lead the force into 2011 and beyond".
Mrs Spence, who is 54, has pledged to continue to work hard for the force and the county until her last day.
She remains committed to Cambridgeshire and looks forward to remaining part of county life after her retirement and supporting initiatives that promote the wellbeing of local people.
She also plans to spend more time with her husband, John, while considering new opportunities and admits she will not be able to sit still for long.
Ruth Rogers, chair of the Police Authority said: "Julie Spence has been a powerful force for improvement and development in Cambridgeshire. Her integrity and honesty is recognised by the public and by all those who work within the force.
"Julie has provided a sound legacy for her successor and I look forward to leading the Police Authority process to ensure we appoint a worthy successor".
Mrs Spence joined Cambridgeshire Constabulary in 2004 as deputy chief constable and became acting chief constable in June 2005.
