When Frontline member Anthony Loyd found Shamima Begum in al-Hawl refugee camp, northern Syria, he helped unearth a series of unanswered questions for Western societies – and kickstarted a national debate in the United Kingdom.

When it comes to citizens returning from IS territory, what are our legal and moral responsibilities? Is there a two-tier system developing, with citizenship as privilege for the children of Muslim immigrants, and nationality as right for European ‘natives’?

With first-hand reporting from Anthony Loyd, and comment from columnist Nesrine Malik and expert on jihadist movements Shiraz Maher, we’ll be discussing the fallout of British Home Secretary Sajid Javid’s decision to revoke Shamima Begum’s citizenship. This discussion will be chaired by presenter of BBC HardTalk Stephen Sackur.
