Putin, 66, who jealously protects his privacy and that of his close family, was replying to a question posed by a reporter at his annual press conference, which focused mainly on international relations and the state of the economy.
“As a respectable person, I will have to do this at some point,” Putin said, smiling. Putin was married to Lyudmila Putina from 1983 until their divorce, announced in 2013.
Their daughters, Katerina and Maria, both in their early 30s, are not involved in politics and have stayed firmly out of the limelight.
Since he divorced his wife Lyudmila, rumours have swirled around Putin’s personal life. One Russian newspaper report said he was in a relationship with Alina Kabaeva, a former Olympic gymnast, though Putin rejected the assertion.
