Russia's president says his daughters avoid the limelight

Russian President Vladimir Putin, who is notoriously protective of his family's privacy, made a rare reference to his two daughters on Thursday, saying they lived in Russia and stayed clear of business and politics.

But he avoided saying where they worked.

"They are taking the first steps in their careers, but are making good progress. They are not involved in business or politics," Putin said of his daughters, Maria and Katerina.

"They have never been 'star' children, they have never got pleasure from the spotlight being directed on them. They just live their own lives," he told an annual news conference.

"They live in Russia ... They have never been educated anywhere except Russia. I am proud of them, they continue to study and are working. My daughters speak three European languages fluently."

He cited security concerns for not giving any further details about them.

Reuters reported last month, citing multiple sources who know her, that Katerina was working in a senior post at Moscow State University and that she had described herself as the spouse of Kirill Shamalov, a shareholder in petrochemicals company Sibur.

Katerina uses the surname Tikhonova, derived from the name of her grandmother, according to the Reuters report.
