The Duke and Duchess of Cambridge and Prince Harry are to join the families of Westminster terror attack victims at a special service today, two weeks after Khalid Masood's murderous rampage.
Survivors, witnesses and members of the emergency services will come together for the multi-faith Service of Hope at Westminster Abbey - just minutes from where the attack unfolded.
Home Secretary Amber Rudd, Metropolitan Police Acting Commissioner Craig Mackey and London Mayor Sadiq Khan will also be among the congregation.
Five people, including terrorist Masood, were killed and dozens of others injured in the 82-second atrocity on Wednesday March 22.
American tourist Kurt Cochran, 54, retired window cleaner Leslie Rhodes, 75, and Aysha Frade, 44, died when the Muslim convert drove at pedestrians on Westminster Bridge.
The 52-year-old attacker was shot dead by armed police after fatally stabbing Pc Keith Palmer, 48, in the Palace of Westminster's cobbled forecourt.
The service, which will take place at noon, will be broadcast live on the BBC.
