I don't know how much of this you know, but there are several "dissident" republican and loyalist terror groups that have remained active since the Good Friday Agreements. The Omagh bombing, with the biggest loss of life of any attack in the Troubles, was carried out by dissident republicans after the agreement. The last republican bombings on British soil (not in Northern Ireland) were by the Real IRA in 2001, but they've continued in Northern Ireland, including in the past few years.
I know about the IRA in general from the news & living in the UK. I hadn't realised splinter groups were still at it.
I don't tend to read the news -- so haven't heard much about Sinn Fein[0] recently, for example. Looking up SF, I've just learned they are left-wing. I'd assumed they were right-wing nationalists.
Guess the answer to how much I know about this subject is, a wee bit.
The research & library creation is illegal. That's a bit much:
'Research resulting in the creation of a library of documents providing information of a kind likely to be useful to a person committing or preparing an act of terrorism
— specifically information regarding the manufacture of explosive substances, the construction of explosive devices, and tactics used by terrorist organisations.'
No, it's not. It's the entirety of the first numbered point (of six) on page 1; all six of the numbered points there, as well as the paragraph leading into the numbered list and all but the last two paragraphs of page 2 address Count 1. Count 2 is addressed in the penultimate paragraph of page 2, and Count 3 is addressed in the final paragraph of page 2, which carries over onto page 3. The remainder of the document is not recounting the offenses but discussing other sentencing factors.
There are only 3 counts (as stated at the very beginning of the document), so even if the beginning of the discussion of each count weren't explicitly marked in a parenthetical, it would be easy to see that the numbers of the six-item numbered list could not be count numbers.
All the numbered paragraphs are subject to the rider "As the Particulars of that offence make clear, with the intention of assisting another to
commit acts of terrorism, you engaged in conduct in preparation for giving effect to that intention
namely:"
