Should the UK deport immigrants who are considered to be promoting terrorism?

Under section 15 of the Immigration Act 1971, the Home Secretary has a very broad power to deport any foreign national whose removal from the UK he or she believes would be ‘conducive to the public good’. Although the Home Secretary enjoys a very broad ground to deport foreign nationals, this power is traditionally exercised when a foreign national is engaged in criminal activity or deemed a threat to the national security of the UK.

Yes, but only if they aren't a greater threat from abroad

First you would have to define the term "terrorism" and remove any racist implications. Then you would have to consider what the appropriate response would be to a domestic "terrorist". Then you would need to consider why the foreign actor is different. If someone could be proven to be orchestrating an act of political violence against a civilian population, they would need to be removed from the populace, whether that be gaol or deportation. My preference would be gaol since they would be more likely to foment danger more freely elsewhere.

Maybe they should be treated as any UK national would be - just a thought (terrorism is not just a foreign problem) x

 @9LW9HFSanswered…2yrs2Y
