Sarah Palin says she will step down as Alaska's governor, fueling speculation the former Republican vice-presidential candidate will make a run for the White House in 2012.
Palin, who made the sudden announcement at her home in Wasilla, Alaska, told reporters Friday that her last day on the job will be July 26.
Neither Palin nor her spokesman would talk specifically about her future plans, but she said that she wanted to make a "positive change outside government."
Palin also hinted that she was frustrated with her current political title.
"I cannot stand here as your governor and allow the millions of dollars and all that time go to waste just so I can hold the title of governor," Palin said.
In a Twitter message posted later in the day, Palin said she would soon release more details: "We'll soon attach info on decision to not seek re-election ... this is in Alaska's best interest, my family's happy ... it is good. Stay tuned"
Palin was elected as Alaska governor in 2006 but rose to national prominence last year when former presidential candidate Sen. John McCain picked her as his running mate.
Palin's popularity in her home state has declined amid months of partisan battles at the state legislature. Her term was set to expire in 2010.
Lt. Gov. Sean Parnell will take over the governor's office and will be inaugurated in Fairbanks at the end of July, according to a Palin spokesman.
The announcement also surprised Parnell, who only found out about Palin's decision on Wednesday evening.
