A key political ally of Vladimir Putin has adopted a child seized from a Ukrainian children's home, according to documents uncovered by BBC's Panorama.
Sergey Mironov, the 70-year-old leader of a Russian political party, is named on the adoption record of a two-year-old girl who was taken in 2022 by a woman he is now married to.
Records show the girl's identity was changed in Russia.
Mr Mironov has not responded to requests for comment.
The child, originally named Margarita, was one of 48 who went missing from Kherson Regional Children's Home when Russian forces took control of the city.
They are among about 20,000 children who, according to the Ukrainian government, have been taken by Russian forces since the start of the full-scale invasion in 2022.
Earlier this year the International Criminal Court (ICC) issued arrest warrants for President Vladimir Putin and his Commissioner for Children's Rights, Maria Lvova-Belova, for the alleged illegal deportation of Ukrainian children to Russian-controlled territory, with the intention of permanently removing them from their own country.
The Russian government says it does not deport Ukrainian children, but does evacuate them to give them protection from the war.
The BBC worked with Ukrainian human rights investigator Victoria Novikova to find out what happened to Margarita and the other children. Ms Novikova has prepared a dossier of new evidence for Ukraine's prosecutor-general's office, which will hand it to the ICC.
The mystery surrounding Margarita began when a woman in a lilac dress turned up at Kherson's children's hospital, where the 10-month-old was being treated for a bout of bronchitis in August 2022.
Margarita was the youngest resident of the local children's home, which looked after children who had medical problems, or whose parents had lost custody of them or had died.
Margarita's mother had given up custody shortly after her birth, and her father's whereabouts were unknown. Dr Nataliya Lyutikova, who led infant treatment at the hospital, said she was a smiley baby who loved cuddling people.
Margarita was just 10 months when she was taken from the home
The woman in lilac introduced herself as "the head of children's affairs from Moscow", Dr Lyutikova recalls.
Kherson - now back under Ukrainian control - was then in its sixth month of Russian occupation.
Soon after the woman left, Dr Lyutikova says she received repeated phone calls from a Russian-appointed official, who had recently been put in charge of the children's home. The official demanded that Margarita be sent back to the home immediately.
Within a week, Margarita was discharged from the hospital. The following morning, staff at the children's home were asked to prepare her for a journey.
"We were afraid, everyone was afraid," said Lyubov Sayko, a nurse at the home.
She described how Russian men - some in military-style camouflage trousers, one in black glasses and holding a briefcase - had arrived to collect the girl.
