Free speech activists condemn UK entry ban for two leftwing US commentators

Cenk Uygur and Hasan Piker, who have both been accused of propagating antisemitism, barred from visiting for event

The UK is failing to protect freedom of speech, prominent activists have said, after the government banned two leftwing US political commentators from entering the country to attend speaking engagements.

Cenk Uygur, the host of the Young Turks online political talkshow, and Hasan Piker, who runs his own hours-long stream each day, were both due to appear at SXSW London, while the former said he had also been due to speak at an event run by University of Oxford students.
