LOWELL -- The clerk of courts for Middlesex County, Michael Sullivan, will challenge Middlesex District Attorney Marian Ryan in next year's election.

Sullivan, who ran for district attorney in 1998 and called Ryan a friend, said Monday he's the best candidate for the job because of his experience in prosecution and administration. He plans to make a formal announcement on his candidacy early in the new year.

"I decided to run based upon my own personal background," Sullivan said. "It's something I always wanted to do... I believe I have what it takes to reclaim and reignite what had traditionally been a strong office."

Sullivan, 54, was a Cambridge city councilor and mayor, following in the footsteps of his father and uncle, who both also served in those two capacities. He has been clerk of courts since 2007, and was re-elected last year.

Ryan, 58, was appointed district attorney in April by Gov. Deval Patrick after Gerard Leone resigned to take a private-sector job. Her campaign to keep the seat next year will be her first run at elected office.
