UK terror threat level downgraded from 'substantial' to 'severe'

Joint Terrorism Analysis Centre changes threat status to its lowest level since 2014 The UK's national terrorism threat level has been downgraded from severe to substantial for the first time in five years, the home secretary has said, although this means a terrorist attack is still likely. In a written statement to parliament, Priti Patel announced the decision by the Joint Terrorism Analysis Centre (Jtac) whose decisions are taken independently of ministers.
