Vladimir Putin's two daughters are kept well away from the public spotlight, with his grandchildren even more of a closely guarded secret.
The Russian president has been interviewed countless times over the years, but one in appearance in the summer of 2017 promised to give "unparalleled access" to the world leader, described as the most controversial, dangerous, powerful and influential man on the planet.
The series of interviews, carried out by Oliver Stone, were televised over four nights in the US, with a healthy and affable Putin speaking candidly from inside the Kremlin - although carefully avoiding some of the trickier questions, the Mirror reports.
In one direct question, Mr Stone asks: "Are you a grandfather yet?" And Putin says yes and nods, he is then asked if he is a good granddad and does he play with them in the garden.
Putin replies: "Very seldomly."
Mr Stone then tells Putin: "You are a very lucky man, two good children."
A smirking Putin replies: "Yes, I'm proud of them," he adds but doesn't offer his interviewer any more details.
Casey Michael from the Kleptocracy Initiative at the Hudson Institute told CNN: "He acknowledged that he was a good family man, but he is more interested in appearing with the Russian Orthodox Church or military situations or riding shirtless on the back of a horse, to project his power, that's power.
"Family in many ways is weakness."
Another analyst believes Putin has a darker reason for keeping his family out of the spotlight.
Professor Howard Stoffer from the University of New Haven added: "He doesn't want to be vulnerable to anybody else doing something to him if a lot is known about his family."
Officials in the US and the UK believe Putin has hidden many of his asset with family members.
Speaking in 2015 about his daughters, the Russian leader added: "My daughters live in Russia and studied only in Russia, I am proud of them.
"They speak three foreign languages fluently. I never discuss my family with anyone."
"Every person has a right for their fate, they live their own life and do it with dignity."
Putin has two daughters with his ex-wife Lyudmila, 36-year-old Maria Vorontsova and Katerina Tikhonova who is 35.
Maria studied biology at St Petersburg University and medicine at Moscow State University and is now academic, specialising in the endocrine system.
She co-wrote a book on stunted growth in children, and is listed as a researcher at the Endocrinology Research Centre in Moscow.
BBC Russia also identified her as co-owner of a company planning to build a massive medical centre.
She is married to Dutch businessman Jorrit Joost Faassen, who once worked at Russian state energy giant Gazprom, although they have reportedly separated.
She is said to support her father and has cast doubt over international reporting of Russia's invasion of Ukraine.
Katerina, appeared in the spotlight in 2017 when she came fifth in an international rock and roll dance competition, she later married the same year.
She is now in academia and business and made a brief appearance on Russian state media in 2018 to talk about neurotechnology and also at a business forum in 2021.
In neither case was her relationship to the president mentioned.
Putin remains tight-lipped about his grandchildren and rarely discusses them publicly.
In 2017 he said: "Regarding my grandchildren, one is already in nursery school.
"Please understand, I don't want them to grow up like some kind of royal princes. I want them to grow up like normal people."
