The chair determined that had Andrews not already resigned, he would have been dismissed without notice.
The force’s director of people Iain Gibson said: “Policing is a privilege, and the actions of former PC Andrews fall considerably below the standards of professional behaviour that we expect.
“Drink driving can have devastating impacts on individuals, other road users and the community at large and for an officer to be found over the limit is completely inexcusable.
“The public’s trust and confidence in the police is essential for policing to be able to provide the best possible service, and former PC Andrews’ actions threaten to undermine all the excellent work that the overwhelming majority of officers do to keep the public safe on our roads.”
