British prosecutors said on Thursday they had authorised police to charge Ali Harbi Ali, 25, with murder of lawmaker David Amess, who was stabbed to death on Friday at a meeting in his constituency.
"We will submit to the court that this murder has a terrorist connection, namely that it had ideological motivations," Nick Price, Head of the Crown Prosecution Service Special Crime and Counter-Terrorism Division.
"He has also been charged with the preparation of terrorist acts. This follows a review of the evidence gathered by the Metropolitan Police in its investigation."
