New York, July 4 (ANI): Sarah Palin’s daughter’s ex-boyfriend Levi Johnston is planning to pen a tell-all book.

According to Johnston’s bodyguard/publicist, Tank, he is planning to write a book that may also focus on the Wasilla, Alaska, political family.

“There are still many untold stories about the Palins,” the New York Post quoted Tank as saying.

Meanwhile, Palin has decided to step down from the post of Alaska Governor.

Her decision to resign from office, when she still has more than a year left to complete her term, has evoked mixed reactions.

Palin’s decision to quit at the end of the month has left political observers scratching their heads, and wondering whether this is the beginning of her run for the White House in 2012, or the end her career in politics. (ANI)
