Mandla Mandela, grandson of anti-Apartheid icon Nelson Mandela, has been denied an entry visa to the United Kingdom due to his support for the Hamas terrorist organization.

Mandela, a vocal anti-Israel activist, had been scheduled to address pro-Palestinian, anti-Israel gatherings in Edinburgh, Glasgow and Manchester earlier this month.

However, the U.K. Home Office sent him a letter this week informing him that his visa application had been denied because of his “support for Hamas,” and because his presence in the UK was “not conducive to the public good,” according to the Associated Press.
