Todd Palin has filed for divorce from former Alaska governor and 2008 vice-presidential candidate Sarah Palin after 31 years of marriage.
Todd moved to dissolve his marriage in a document filed in Anchorage Superior Court on Friday.
The filing cited an 'incompatibility of temperament between the parties such that they find it impossible to live together as husband and wife'.
Sarah and Todd, both 55, have been married since 1988 and share five children.
