Shamima Begum who joined the Syrian militancy group Islamic States (IS) is a citizen of Bangladesh as well – this was the UK’s reason to cancel out her British citizenship. In reaction, Bangladesh has said that Shamima is not a Bangladeshi citizen. So there’s no way she could come to Bangladesh now.
This speech from Bangladesh has now challenged the validity of the cancellation of Shamima’s British citizenship. The cancellation act has been criticized because the British home minister didn’t have a discussion with the Bangladeshi counterpart regarding this and also didn’t follow an appropriate procedure to do this.
