Ahhh, I see the Shamima Begum option is being mentioned. The fantasy of the racists that the UK will be able to deport most of its 4 million Muslims to Pakistan or Bangladesh, by arguing that they are dual nationals and so we can strip them of their UK passports and then deport them. Bliss, eh?
Well, no.
First, it was never clear that Shamima Begum was entitled to a Bangladeshi passport. If she was, it was only until she was 18. She is now well over 18, so that ship has sailed.
Much more importantly, though, she was outside the UK when this happened. It's a hell of a lot easier to cancel a passport than to remove somebody. If she had been in the UK when the government did that, and said "You're going to have to leave", the only country that could have taken her in was Bangladesh. But they were under no obligation to do so.
I think perhaps people don't understand how deportations work. They are arranged through diplomatic channels. An Albanian commits a crime in the UK, or a Brit commits a crime in Spain, and the ambassadors and their deputies get together, and decide that it's best if the person is sent home, so that's what happens. But it's a bilateral process. You can't just put the person on a plane, fly it to Tirana, and push them down the stairs onto the tarmac. You will note that Ms Begum is not in Bangladesh, because they quite rightly don't want her.
So there is zero realistic possibility of forced deportations. Which in one way is kind of a pity, because Stephen Yaxley-Lennon, a man with an extensive criminal record including drugs charges and mortgage fraud in addition to his "patriotic" activities, is also an Irish citizen. In fact he is only able to live patriotically in Spain because as an EU citizen he can't be denied entry due to his criminal record, which would be the case if he was there on a visa.
So, sorry, racists, but the deportation option is out. We await your proposals for other solutions.
