Liberal Democrat Leader Jo Swinson said:
“Our emergency services have once again displayed the courage and professionalism that keeps us safe everyday. I am hugely grateful to each and every one of them.
“My thoughts are with the people who were injured and all those affected by this appalling display of violence.
“Today’s incident reminds us that we can never take our security for granted. We must never forget the vital work that our police and security services do to keep us safe.
“Those who seek to terrorise us, divide us or undermine our freedoms will never succeed.”
