CEP Senior Adviser Ian Acheson writes: "Yesterday, the appeal court ruled that in absentia, she had not been afforded sufficient opportunity to defend herself against the British Government’s decision to strip her of UK citizenship. She must now return to the UK to present her case. This was an entirely predictable outcome from an ill-conceived knee-jerk decision that had too much to do with populism and far too little to do with smart national security. We should have had Begum and her associates with British citizenship back on these shores long ago."
