Ottawa Mayor Larry O'Brien announced Wednesday that he is stepping down from the Ottawa Police Services Board.

Mike Patton, a spokesman for the mayor, said O'Brien wanted to serve on the board while it was selecting a new police chief and while he was in the process of getting his first city budget passed.

However, he is now comfortable with the new chief, Vern White, and with the way the board is heading, Patton said.

O'Brien said he was concerned about the amount of preparation time required to do a good job on the board, and felt other areas needed his attention more, such as his "transformation" agenda.

In April, O'Brien said he was launching the 1,000-day campaign in a bid to change the way services are delivered and decisions are made at city hall.

O'Brien was one of three council members on the Police Services Board, which also includes three provincial appointees and one citizen appointed by city council.

Ottawa city council passed a budget in February that boosted taxes used to fund police.

White was officially named the city's new police chief in March and was sworn into the position in May.
