A 2006 Olympic ice dancing champion says she is to marry President Vladimir Putin's spokesman later this summer.

Tatiana Navka has been dating Dmitry Peskov, a father of three from two previous marriages, for several years and they had a daughter in August last year. Despite frequent public appearances together Peskov has not spoken publicly of his relationship with Navka, who also has a daughter from a previous relationship.

Navka, 40, said in an interview with the state-owed R-Sport news agency on Thursday that the wedding is planned in the Black Sea resort of Sochi, scene of the Winter Games in 2014. She didn't disclosed the date.

Peskov, 47, has said he would not comment on his private life, which is "nobody else's business."
