His daughters' faces were never shown apart from in historic images from their childhood.
Putin has said previously of his daughters: 'They are taking the first steps in their careers, but are making good progress. They are not involved in business or politics.
'They have never been "star" children, they have never got pleasure from the spotlight being directed on them. They just live their own lives.
'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.'
In 2015 it was revealed that Maria's sister is known as Ekaterina Tikhonova - now 32- and was put in charge of a £1.1billion expansion of Moscow State University, the country's most famous higher education institution.
