Another year, another Eurovision. Ireland finished respectably in 16th place - though our neighbours in the UK could only manage 24th. To be fair, however, SuRie had an excuse: her song was interrupted by a protestor.

"The EBU regrets a stage invasion took place during the UK performance. The person responsible is currently in police custody," it read. "The UK singer SuRie and her team were offered the option to sing again but decided not to because they were extremely proud of her performance and have decided that there is absolutely no reason to perform the song again." https://twitter.com/HuffPostUKEnt/status/956087284885000192?tfw_site=JOE_co_uk&ref_src=twsrc%5Etfw&ref_url=https%3A%2F%2Fwww.joe.co.uk%2Fentertainment%2Fdermot-oleary-confronts-stage-invader-at-national-television-awards-in-unaired-moment-159050 At the NTAs Dermot O'Leary was forced to confront him and see him off stage. Well done, Dermo!
