The daughter of a former Russian prime minister is under fire from both Russia and Ukraine for accepting the job of a deputy governor in a Ukrainian region.

Maria Gaidar's appointment as deputy governor of Odessa, now led by former Georgian President Mikhail Saakashvili, has been painted as a betrayal in Russia. In Ukraine, she has been criticized for being hesitant to denounce Russia's annexation of the Crimean peninsula.

Gaidar, 32-year-old daughter of the 1990s prime minister Yegor Gaidar, told reporters in Kiev on Monday that she supports Ukraine's territorial integrity and that she would not renounce her Russian citizenship.

In Moscow, the human rights ombudsman Ella Pamfilova said Gaidar's Moscow-based charity foundation could be stripped of a presidential grant following her appointment.
