Jamala won the contest in 2016 and fled Kyiv in March.
A former Ukrainian Eurovision winner says "it would be fair" to hold next year's song contest in the UK if her home country can't.
Jamala, who won in 2016 and fled Kyiv in March following Russia's invasion, says it should be staged in a "peaceful place".
Ukraine's Kalush Orchestra won this year's competition but organisers are looking at holding it in Britain, which came second.
