LONDON — SXSW London 2026 is unfolding under a cloud of controversy after its organizers announced that rapper Earl Sweatshirt would not perform due to an unspecified “accident,” while political commentators Cenk Uygur and Hasan Piker were barred from entering the UK by the Home Office. The cancellations have sparked accusations of censorship, with Piker accusing festival organizers of failing to defend them, and critics questioning the UK government’s use of immigration powers to silence dissent.

The festival, running June 1–6 in Shoreditch, had been billed as a platform for diverse voices in music, technology, and politics. But the last-minute changes have left attendees and activists questioning the event’s commitment to free expression—especially as the UK government faces growing scrutiny over its handling of visa denials tied to political speech.

For fans of Earl Sweatshirt, the news arrived via an Instagram post from SXSW London organizers, who stated that the rapper had “met with an accident” preventing his appearance at Shoreditch Town Hall on June 2. The post added: “We’re sad that we won’t be able to welcome him to London this year, and we know that this will be disappointing to fans. His wellbeing must come first.” The rapper’s set was replaced by MIKE, according to the festival’s updated lineup.

Cenk Uygur and Hasan Piker Barred from UK: Festival Silent on Censorship Allegations

Meanwhile, the cancellation of Cenk Uygur and Hasan Piker—both prominent critics of Israeli government policies—has ignited a firestorm. The UK Home Office revoked their Electronic Travel Authorisations (ETAs), citing concerns that their presence “may not be conducive to the public good.” The decision came hours before their scheduled appearances, leaving organizers scrambling to adjust the program.

Piker, who was set to speak at an Oxford University event and chair a panel at SXSW, took to X (formerly Twitter) to condemn the festival’s response, calling organizers “actual fucking losers” and vowing never to work with them again. He also urged ticket holders to demand refunds, framing the cancellation as a failure to stand against government overreach.

sxsw was a minor part of my trip to the uk, they totally didn’t defend me or cenk at all, they’re actual fucking losers and i will never work with them for the rest of my life. If you bought a ticket expecting to see me you should demand a refund.

The UK government’s decision to block Uygur and Piker follows a pattern of targeting critics of Israel. Zarah Sultana, MP for Coventry South and a vocal advocate for Palestinian rights, wrote to Home Secretary Shabana Mahmood demanding the ban be reversed. “This raises serious questions about freedom of expression and whether immigration powers are being weaponised to silence political dissent,” Sultana said in a statement shared on X.

The UK government has barred Hasan Piker and Cenk Uygur from entering the country over their criticism of Israel. Meanwhile, war criminal Isaac Herzog, whose statements were cited in the ICJ genocide case against Israel, was welcomed at Downing Street with open arms.

Festival’s Stance: “Diverse Voices, But No Endorsement”

In a statement, SXSW London acknowledged the cancellations but distanced itself from the political implications, stating: “Decisions on entry to the UK are a matter for the Home Office and the individuals concerned. SXSW London’s role is to convene a broad range of diverse voices and perspectives.” The festival’s spokesperson added that it remains committed to fostering “open dialogue and exchange of ideas,” despite the controversies.

However, the response has drawn sharp criticism from Ash Sarkar, a journalist for Novara Media who was set to chair Piker’s panel. Sarkar initially called on SXSW to allow Uygur and Piker to contribute remotely, but later announced she was pulling out of the event entirely, writing: “If I were in their shoes, I would hope that any organisation which invited me to speak, and had their programming interfered with by the Home Office, would have had the minimal expected integrity to offer some defence of lawful free expression.”

I was supposed to chair the @hasanthehun discussion at SXSW this week, who’s been banned from entering the UK by Shabana Mahmood. First of all, @sxsw must facilitate a way for Hasan and Cenk to contribute remotely, as a bare minimum refusal to comply with government censorship.

I pulled out of SXSW London, and I hope other speakers and chairs do too.

Broader Context: SXSW London’s History of Controversy

This isn’t the first time SXSW London has faced backlash over its lineup. Last year, multiple artists and speakers pulled out in protest after the festival announced appearances by former UK Prime Ministers Tony Blair and David Cameron. Critics accused the event of “artwashing”—using cultural platforms to legitimize figures accused of complicity in the ongoing conflict in Gaza.

In response, SXSW London’s organizers stated that the festival “respects everyone’s views and positions” and aims to create a space for “diverse debate.” Yet, the inclusion of Blair and Cameron—both of whom have faced international criticism for their roles in foreign policy controversies—sparked accusations that the festival was prioritizing access over accountability.

What Happens Next?

As of now, SXSW London continues with its program, featuring over 800 speakers across music, tech, and media. However, the cancellations have reignited debates about the UK’s immigration policies and the role of cultural festivals in amplifying—or silencing—controversial voices.

For those affected by the changes, including ticket holders expecting to see Piker or Uygur, the next steps remain unclear. The UK Home Office has not provided further details on its decision, and legal challenges to visa denials based on “public good” grounds are rare but not unheard of. Meanwhile, SXSW London has not issued a statement beyond its initial acknowledgment of the cancellations.

One thing is certain: the incident will likely fuel ongoing discussions about free speech, government overreach, and the ethics of global cultural events in an era of heightened political polarization.
