Sir Keir Starmer says terrorism has changed and we face a new threat as he announces the details of an inquiry into the state failings that left Axel Rudakubana able to kill three young girls in Southport last summer. 
  
Rudakubana was known to have been obsessed with violence and had been referred to the Prevent counter terrorism programme three times in the 17 months before the murders.  
  
On today's Sky News Daily, Niall Paterson is joined from Southport by North of England Correspondent Katerina Vittozzi and Crime Correspondent Martin Brunt to discuss what the inquiry will achieve and why so many details of the case can only be revealed now. 

Plus, Niall’s also joined by chief political correspondent Jon Craig for the political reaction.
