Former US vice President Al Gore and wife Tipper are separating after 40 years of marriage.
In an email circulated among the couple's friends the Gores said it was “a mutual and mutually supportive decision that we have made together following a process of long and careful consideration”.
A Gore spokeswoman declined to comment further. Al Gore lost the 2000 Presidential election to George W. Bush.
He has since campaigned worldwide to draw attention to climate change, which in 2007 led to a Nobel Peace Prize and an Oscar for the documentary An Inconvenient Truth.
