The British government has banned left-wing political commentators Hasan Piker and Cenk Uygur from entering the U.K. They were scheduled to speak at the SXSW London festival and the Oxford Union Society. The U.K.'s Home Office said that it was canceling their travel permits “on the grounds that their presence in the U.K. may not be conducive to the public good.” Both Piker and Uygur are outspoken in their criticism of Israel. Uygur posted on social media, “I've been banned for criticizing Israel. Are we free anymore?” Piker also said, “The UK has revoked my visa as well. All at the behest of Israel.”
