Ken McCallum, head of MI5, has warned that rightwing extremists with anti-migrant views are increasingly considering terrorist attacks against immigration centres and asylum hotels in the UK.
McCallum identified a shift from radicalised rightwing sentiment to violence as "the most marked trend" in MI5's caseload over the past year. He linked this pattern to a rise in the overall UK terror threat level.
The warning reflects a documented escalation in how anti-immigration and anti-Muslim ideology translates into potential violent action among extremist networks tracked by British intelligence.
