Alaska Gov. Sarah Palin says she is resigning from office.

She didn't say why she decided to step down, but the surprise
announcement stirred speculation that she would focus on a bid for the 2012 Republican nomination for president.

The former Republican vice presidential candidate made the announcement from her home in suburban Wasilla on Friday morning.
She said she would step down July 26.

Spokesman Dave Murrow says Lt. Gov. Sean Parnell will be inaugurated at the governor's picnic in Fairbanks at the end of the
month.

Palin was first elected in 2006 on a populist platform. But her popularity has waned as she waged in partisan politics following her return from the presidential campaign.
