Why the UK banned Hasan Piker and Cenk Uygur

Available for over a year

On Sunday, two prominent left-wing political commentators in the US — Hasan Piker and his uncle, Cenk Uygur – said they had been barred from visiting the UK. Both men were due to appear at the SXSW London festival, but say the British government blocked them from entering the country because of their criticism of Israel. The British government confirmed that it had denied them entry on the grounds that their presence in the UK “may not be conducive to the public good” but did not elaborate further. Their cases have sparked renewed debate about the limits of free speech in the UK. We speak to American political activist Shabbos Kestenbaum – who was due to debate Cenk Uygur in London – and to the legal academic and host of the BBC’s The Law Show, Joelle Grogan.
