A Co Down-born police commander has seen off competition from senior officers in London and Dublin to be named the PSNI's new Chief Constable.
Current PSNI Assistant Chief Constable George Hamilton will take over from outgoing chief Matt Baggott when he retires in September, the NI Policing Board announced.
Mr Hamilton was vying with Metropolitan Police Assistant Commissioner Cressida Dick and Garda Assistant Commissioner Derek Byrne for the high-profile job.
Chief Constable Baggott came from Leicester to the post in Northern Ireland in 2009. Hugh Orde was his predecessor.
The annual salary for the post is £195,000 (€239,000) plus benefits.
The father-of-four from Bangor was the only officer in the PSNI eligible to apply for the post after the Policing Board, which is the PSNI's oversight body, opted to retain the controversial criterion that required all candidates to have served at senior command level outside Northern Ireland.
He served as assistant chief constable in Strathclyde from 2009 to 2011 and also worked in England for three years on a range of police training and organisational development projects.
Mr Hamilton first joined the Royal Ulster Constabulary in 1985 and steadily worked his way through the ranks, including detective superintendent, detective chief inspector and district commander.
He holds a Bachelor of Arts degree in politics and economics and a Masters in business administration.
He is a member of the Institute of Directors and the FBI Law Enforcement Executive Leadership Association.
As Assistant Chief Constable to Mr Baggott, he is currently responsible for rural policing in Northern Ireland, an area that covers approximately 11,700 sq km and a population of approximately 900,000.
A nine-member Policing Board appointment panel interviewed all three candidates throughout today.
The choice of Mr Hamilton was approved by Stormont Justice Minister David Ford.
Policing Board chair Anne Connolly said: "I am pleased to announce that the Policing Board has appointed ACC George Hamilton as the new PSNI Chief Constable.
"The position has been accepted and the formal date of appointment will be confirmed in the next number of days.
"ACC Hamilton brings wide-ranging experience to this important job and has the necessary skills to lead the PSNI forward.
"As a board, we are looking forward to working closely with the new Chief Constable in dealing with the issues facing policing and agreeing a programme of work that supports community confidence in policing."
Ms Connolly also thanked the unsuccessful candidates.
"The Board was very impressed with the calibre of candidates who applied for the Chief Constable job. They had a vast amount of policing expertise and I would like to thank each of them for their interest," she said.
Minister for Foreign Affairs Eamon Gilmore welcomed Mr Hamilton's appointment and said: "George Hamilton brings a wealth of experience, expertise and dedication to the role.
"I know from my many friends in Northern Ireland that he is greatly admired by his colleagues in the PSNI and across the whole community."
Mr Baggott is stepping down in the autumn after five years in the role.
There is currently a period of significant flux at the top command levels of the PSNI. At the end of March, Deputy Chief Constable Judith Gillespie retired.
Mr Hamilton faces a stacked in-tray when he takes over the reins from Mr Baggott.
The PSNI is currently trying to balance a dwindling budget with its ongoing fight against dissident republican terrorism.
Its resources are also being stretched trying to fulfil its obligations to both investigate and provide information to the Coroners Service in regard to historic Troubles-related cases.
Also, last year almost 850 officers were injured in rioting linked to disputes over flags and parades.
With Northern Ireland's politicians having failed to strike any deal to resolve the issues, the spectre of a recurrence of disorder this summer again looms large.
Congratulations & best wishes to George Hamilton on his appointment today as Chief Constable of the PSNI.— Martin McGuinness (@M_McGuinness_SF) May 29, 2014
