The 2023 Eurovision Song Contest will be held in the UK next year on behalf of Ukraine, the European Broadcasting Union (EBU) and the BBC have confirmed.
The BBC will host the contest. It has not yet been announced which city will play host.
This was despite Ukrainian entry Kalush Orchestra triumphing at this year's competition in Turin, Italy, with the UK's Sam Ryder coming runner-up.
Ukraine will automatically qualify for the grand final alongside the so-called big five nations - the UK, France, Germany, Italy and Spain, who each get a free pass because of their financial contributions to the event.
It will be the ninth time Eurovision has taken place in the UK - more than any other country.
The bidding process to select the host city will begin this week and will be jointly managed by the BBC and EBU.
Martin Osterdahl, Eurovision's executive supervisor, said: "We're exceptionally grateful that the BBC has accepted to stage the Eurovision Song Contest in the UK in 2023.
"The BBC has taken on hosting duties for other winning countries on four previous occasions.
"Continuing in this tradition of solidarity, we know that next year's contest will showcase the creativity and skill of one of Europe's most experienced public broadcasters whilst ensuring this year's winners, Ukraine, are celebrated and represented throughout the event."
Mykola Chernotytskyi, head of the managing board of Ukrainian broadcaster UA:PBC, said: "The 2023 Eurovision Song Contest will not be in Ukraine but in support of Ukraine.
"We are grateful to our BBC partners for showing solidarity with us.
"I am confident that together we will be able to add Ukrainian spirit to this event and once again unite the whole of Europe around our common values of peace, support, celebrating diversity and talent."
Prime Minister Boris Johnson said the UK would "put on a fantastic contest on behalf of our Ukrainian friends".
He said that in talks with Ukrainian President Volodymyr Zelensky last week they "agreed that wherever Eurovision 2023 is held, it must celebrate the country and people of Ukraine".
"As we are now hosts, the UK will honour that pledge directly - and put on a fantastic contest on behalf of our Ukrainian friends," Mr Johnson said.
Culture Secretary Nadine Dorries said: "The Eurovision Song Contest unites people through the power of music and creativity.
"Following a request from the European Broadcasting Union and the Ukrainian authorities, I'm delighted that the BBC has agreed to step in and host next year's contest.
"I'm just sorry that, due to Russia's continued acts of bloodshed, it has not been possible to host the event in Ukraine, where it should be.
"As hosts, the UK will honour the competition's spirit and diversity, and, most importantly, ensure it reflects Ukraine's recent Eurovision victory and Ukrainian creativity."
In a statement, BBC director-general Tim Davie said: "It is a matter of great regret that our colleagues and friends in Ukraine are not able to host the 2023 Eurovision Song Contest.
"Being asked to host the largest and most complex music competition in the world is a great privilege.
"The BBC is committed to making the event a true reflection of Ukrainian culture alongside showcasing the diversity of British music and creativity."
The UK has hosted the contest eight times; London four times (1960, 1963, 1968 and 1977), and once in Edinburgh (1972), Brighton (1974), Harrogate (1982) and Birmingham (1998).
