Former Republican vice-presidential candidate Sarah Palin has announced she will resign as governor of Alaska on 26 July and not run for re-election. Mrs Palin's term of office was due to end in 2010. Some have speculated that Mrs Palin, who is popular with the Republican Party base, might be preparing to make a bid for the White House in 2012. But a report on NBC news suggested that Mrs Palin intends to get "out of politics for good". Her resignation means Alaska's Lieutenant Governor Sean Parnell will take over as state governor. 'New direction' Polls indicated Mrs Palin was very popular in Alaska during the first few years of her governorship, and although her approval ratings have dipped somewhat since her vice-presidential run, she still enjoys widespread popularity in her home state. Mrs Palin announced her decision in a statement from her home town of Wasilla, Alaska. "I'm taking my fight for what's right in a new direction," she said, as her family looked on. Mrs Palin did not reveal what she intended to do after leaving office, and did not give an explicit reason for her decision not to run for re-election. But in a written statement, she made it clear that once she had decided not to run again, she did not want to hang on in office until her term expired. "Once I decided not to run for re-election, I also felt that to embrace the conventional Lame Duck status in this particular climate would just be another dose of politics as usual, something I campaigned against and will always oppose," she said. The BBC's Kevin Connolly in Washington says Mrs Palin's revelation came out of the blue, as most Americans were turning to the celebration of Independence Day on 4 July. She offered no single clear reason for stepping down, our correspondent adds, but the strongest clue was her depiction of what it had been like to be the subject of sustained attack by liberals since she appeared on the national stage.
