Ukrainian President Petro Poroshenko has asked the government to replace Russian-language text with English text in Ukrainian identification documents.
Poroshenko said on November 19 that the request came after a petition from Ukrainians demanding the change to documents that are known as internal passports.
Most internal passports in Ukraine currently carry text in Ukrainian and Russian.
A resident of the western city of Lviv, Svyatoslav Litynskiy, filed a lawsuit in early 2015 against a local passport agency, demanding an internal passport with text only in Ukrainian.
He won the case in May and received such a passport in August.
Ukrainian-Russian relations have hit historic lows since Moscow annexed Ukraine's Crimean Peninsula in 2014 and began supporting pro-Russian separatists in eastern Ukraine.
