The events of yesterday were tragic and heart breaking. My thoughts and prayers are with the victims and their families.
This was a despicable and cowardly act by a man who sought to devastate and to divide. It is thanks only to the extraordinary courage of our Police and first responders that there were not even more casualties.
We owe all of them a debt of gratitude, but none more so than PC Keith Palmer, who lost his own life defending the lives of others. His bravery is an inspiration to all of us, and his loss is a stark reminder of the danger that the men and women of our police forces face every day in order to keep us safe.
The incredible outpouring of love and support we have seen in the last few hours is proof that those who seek to make us afraid or to destroy our way of life will fail. We will not allow this tragedy to divide us or to deter us from democracy.
