Wireless Festival boss stands by Ye headlining concerts as sponsors pull out (apnews.com)
The UK government (under Starmer) then banned Kanye from entering the country, and then the festival was cancelled (because he couldn't come).
The UK government did this under the "Non-Conducive to the Public Good" provision in the Grounds for Refusal section of the Immigration Rules.They deem Kanye a threat to public order or to be otherwise not in the public interest. Officials blocked his Electronic Travel Authorization (a digital permit required for short term visitors to UK who don't need visas). The Home Office cited a 'pattern of behavior' involving so called antisemitic remarks including his Heil Hitler track and swastika-themed merch. No specific crime? only a conceived 'pattern'?
(UK banned Tyler the Creator in 2019 because they said his lyrics encouraged violence and intolerance.)
Rockstar Energy withdrew sponsorshop of Wireless Festival over Kanye.
