Degradation "appalling and shameful" according to the Minister of the Interior

Policeman Keith Palmer, 48, was stabbed to death in March 2017 near parliament by Khalid Masood, a 52-year-old Briton converted to Islam and known to the police who had just mowed pedestrians with his car on the Westminster Bridge. A total of five people died in the attack claimed by the jihadist Islamic State (IS) group.

Interior Minister Priti Patel deemed "absolutely appalling and shameful" the degradation of the plaque posed in tribute to the police, also condemning the clashes between far-right activists and the police, who carried out a hundred arrests Saturday.
