The murderous actions of one individual on the streets of Westminster yesterday afternoon will be subjected to full scrutiny and investigation by our Police and intelligence services. It is vital that we await the outcome before any detailed comment.

I join with many others in offering deep respect to those who lost their lives, sympathy and condolence to their loved ones, and a prayer for the recovery of all who were injured.

It seems highly likely that what happened provides an unwelcome reminder of the existence of the threat from terrorism which we all face. However, the instant response by the Police and emergency services has been exemplary, and has been followed by the thorough investigation which is now underway.

I have no doubt that we will reflect on the events of yesterday for a long time to come. This tragedy can only serve to heighten our vigilance, and that of those who serve to protect us all.

Whilst awaiting developments from the ongoing investigation, my thoughts rest with those whose everyday lives were so shockingly interrupted yesterday afternoon.
