Factbox: When are the Eurovision Song Contest semi-finals and final?

Eurovision 2023 has kicked off in Liverpool, northern England, where acts from 37 countries are competing to win the 67th edition of the song contest.

Liverpool is hosting on behalf of Ukraine, which won the contest last with Kalush Orchestra's "Stefania."

Ukraine was unable to stage the event this year, as the winner usually does, because of Russia's invasion.

Britain, which came second, is promising to combine the creativity of Ukraine and the UK under the banner "United by Music."

Who will compete?

There are 37 countries taking part with 31 competing in two semi-finals and 10 going through to the Grand Final.

Ukraine, as the previous winner, automatically progresses to the Grand Final, along with the "big five," comprising the United Kingdom, France, Germany, Spain and Italy.
