Swedish politician claims to be Mitterand's illegitimate son
Hravn Forsne, 25, told reporters that he was the love child of Mitterrand and Swedish journalist Christina Forsne, who has admitted having a 15-year affair with the Socialist leader.
Mitterrand, who died of cancer in 1996 a year after leaving office, was known to have had a daughter outside marriage with a French woman in 1974, in addition to his two sons with wife Danielle.
Christina Forsne, 66, a former Paris correspondent for the Swedish newspaper Aftonbladet, admitted two years ago that she had embarked on a long affair with Mitterrand after meeting him in 1979 during an interview in Sweden.
But Christina, known as Chris in Sweden, always refused to say whether he fathered her son Hravn - born in 1988 when Mitterrand had just won a second seven-year presidential term.
Hravn is now running for election with the conservative pro-free-market Moderate Party in Sweden's September 14 election. "I want to be judged for who I am, not for who my father was," he told local newspaper Kungsbacka-Posten.
"But OK, Francois Mitterrand was my dad."
He said he was speaking out because he believed it was important for voters to know his background.
Forsne, who lives in Kullavik in southwest Sweden, is tipped to win a seat in September, although opinion polls indicate an overall victory for the Social Democrat Party-led opposition.
