The clause does two things. First, it adds all serious terrorism offences to the scope of the extended sentencing regime. Secondly, it increases the maximum extended licence period for those who receive an extended sentence for serious terrorism offences. I should say that the clause applies to Northern Ireland, and the clause essentially does the same thing as the previous few clauses on extended sentence length and adding some additional offences. That will ensure that there is a consistent approach across the United Kingdom in terms of both offences that are tracked and extended sentences—in the case of Northern Ireland, extended custodial sentences—and that the courts may impose up to a 10-year licence period, should they find that appropriate.
