I commend my right hon. Friend’s powerful statement and add my prayers to hers for those who have died and those who are suffering, and particularly for Keith Palmer, our wonderful and brave police officer. We have faced such threats before from those of twisted and violent ideologies, as the broken stones of the arch through which we enter on a daily basis bear testament to. Time and again, they have failed; they will always fail because we are a beacon of freedom in this place, and that is why they target us. But as they fail, may I urge my right hon. Friend to ensure that as we extoll our righteous defiance in the face of such evil, we lace it with compassion, tolerance and hope?
