BBC News Text:
[Sir Keir is further quoted by the Metro
saying that, in the past,
the "predominant threat was highly
organised political groups with
clear political intent" like al-Qaeda and that,
while that threat remains,
a new one is posed by people
"desperate for notoriety,
sometimes inspired by traditional terrorist groups,
but fixated on that extreme violence,
seemingly for its own sake".]
