It's Eurovision 2021 semi-final week - here's all you need to know if watching from the UK.
There will be two live semi-final shows for Eurovision this year, determining which countries will make the grand final on Saturday.
As one of the Big Five countries along with Spain, Germany, France and Italy, the United Kingdom does not have to qualify from the semi-final stage of the competition and will gain automatic access to the Saturday Grand Final. The Netherlands, as host, also has automatic qualification to the Grand Final.
However the UK will still be able to vote in the second semi-final tonight (Thursday).
The semi-finals will be live on BBC Four, presented by Scott Mills and Chelcee Grimes with Sara Cox standing for Rylan Clark-Neal, who has stepped down due to illness.
Here's all you need to know...

Opening the show is The Netherlands Duncan Laurence, the most recent winner of Eurovision from 2019. Since 2019 Duncan's Eurovision winning song 'Arcade' became a TikTok phenomenon, and earlier this year it returned to the UK charts along with an appearance in US Billboard charts.
