Trustee Sue Huff, shown here in January, resigned as vice-chair of the Edmonton Public School Board Tuesday night. (CBC)A decision to close five central Edmonton public schools two weeks ago prompted trustee Sue Huff to resign her position as vice-chair of the board Tuesday night.

"A big part of the job is to be willing to step in if the board chair is unavailable and speak on behalf of the board with credibility and I just don't think that I can do that anymore," Huff said.

"So I think it's in the best interest for the board for me to step aside and let somebody else step in."

On April 13, a majority of trustees voted to close Capilano, Fulton Place, Eastwood, McCauley and Parkdale schools despite impassioned pleas of parents.

The elementary school program at Spruce Avenue school will also be closed. Huff voted against most of the closures.

Huff will continue in her role as trustee. Her replacement as the vice-chair will be decided at the next board meeting on May 11.
