The prime minister said on Friday that he was "delighted" that Alaa Abd El-Fattah had been reunited with his loved ones in the UK.
Historic posts have since emerged of Mr Abd El-Fattah calling for Zionists to be killed. Shadow Justice Secretary Robert Jenrick has now told Sky News, the prime minister's actions are a "complete disgrace". He added: "This man should not be in the UK and the prime minister of all people should not be out there welcoming him. He's a dangerous individual and it shames our country that we've expended political capital to get him brought here."
