Portland School Board member Elizabeth Brooks is resigning her seat to return to her native England, she said Thursday.

“It is with great sadness that I have to resign my position, but I must return to live in the UK and must move this summer,” said Brooks, who was elected in 2008 and has lived in Portland 18 years.

Brooks will serve through June 30, and her current term was set to expire at the end of the year. The board’s chairwoman said there would not be a special election since the vacancy will be only for six months.

“There is no reason to ask the taxpayers to spend $18,000 to $20,000 on a special election to fill a vacancy of just a few months,” Chairwoman Sarah Thompson said. “I believe that this board can function fine with eight members over the summer and fall.”

Brooks recently chaired the board’s Operations Committee and previously served as president of the Presumpscot School PTO.
