After four terms as mayor of Regina, Pat Fiacco says he will not run again.

Fiacco made the surprise announcement Tuesday at a news conference at a Regina hotel.

"I've had the honour of the people's confidence as mayor for four years. It's a responsibility I've tried to carry with dignity, honour, respect and humility," said Fiacco, his voice choked with emotion. "Today I am announcing that I will not be seeking re-election."

Fiacco, surrounded by family members as he made the announcement, said he's turning 50 this year and is a grandfather, and he wants to spend more time with his family.

After 12 years in the mayor's chair, he said he has no specific plans right now, but is considering his options.

During his time in office, Fiacco became known for his I Love Regina campaign and the debate about a proposed domed stadium.

Before entering politics, Fiacco worked at phone book maker Direct West.

He was first elected in 2000 after defeating long-time incumbent Doug Archer. He was acclaimed in 2003 and then was re-elected in 2006 and 2009.

Municipal elections are set for Oct. 24.

The departure of Fiacco throws the Regina mayoralty race wide open.

So far, at least two people have declared they intend to run.

One of them is local businessman David Robert Loblaw, who ran in 1982 under the name Bob Loblaw.

Also in the running is environmental activist Jim Elliott, who picked up 15 per cent of the vote when he ran against Fiacco in 2009.
