Ali Harbi Ali, 26, from north London, was arrested at the scene and has pleaded not guilty to murder and to preparing acts of terrorism.
On the opening day of his trial at the Old Bailey court in central London on Monday (21), prosecutor Tom Little told jurors that Ali was undoubtedly responsible for the “cold and calculated murder”.
“This was nothing less than an assassination for terrorist purposes,” he said, noting it was “carried out because of a warped and twisted and violent ideology.
“It was a murder carried out by that young man (Ali) who for many years had been planning just such an attack and who was, and is, a committed, fanatical, radicalised Islamist terrorist.”
‘Researched and planned potential attacks’
Amess, a 69-year-old father of five, was a long-serving member of parliament for prime minister Boris Johnson’s ruling Conservative party.
Little said Ali had been determined to carry out a terror attack “for a number of years”, and had bought the knife allegedly used to kill the lawmaker in 2016.
He had researched and planned potential attacks on the Houses of Parliament and other MPs, including targeting the higher-profile senior minister Michael Gove, the prosecutor added.
Ali was spotted outside other MPs’ constituency offices while mobile phone data placed him near parliament seven times between July and September 2021, he noted.
“He’s not a tourist… looking at Big Ben and taking some photographs,” Little told jurors. “This is terrorist planning.”
The 26-year-old defendant appeared in the dock wearing a black robe and black-rimmed glasses.
The killing of Amess, the second of a British MP within five years, shocked the country and led to calls for better security for elected representatives.
In 2016, a right-wing extremist who shouted “Britain first” shot and stabbed Labour MP Jo Cox to death in the febrile run-up to the Brexit referendum.
‘Tricked his way into getting an appointment’
The Old Bailey jury was told that Ali had tricked his way into getting an appointment with Amess by claiming he was moving into the constituency.
The defendant had appeared “relaxed and chatty” moments before he “brutally” stabbed the MP in a “vicious and frenzied attack” shortly after midday on October 15, Little said.
A post-mortem examination showed Amess suffered 21 stab wounds to his face, arms, legs and torso, as well as injuries to both hands that were consistent with defending himself, the court heard.
Afterwards, Ali waved the bloody knife around and said “I killed him, I killed him” while threatening those present to stay away from him, Little added.
“I want him dead. I want every parliament minister who signed up for the bombing of Syria, who agreed to the Iraqi war to die,” he allegedly added.
Jurors heard that the defendant then made a phone call in which he said: “I’ve done it because of Syria. I’ve done it because of the innocent people. I’ve done it because of the bombing. He deserved to die.”
Amess was first elected to parliament in 1983, first representing Basildon in Essex, then nearby Southend West.
Hundreds of locals turned out in the seaside town to pay their respects after his death. Pope Francis praised the Catholic lawmaker’s “devoted public service” in a special message read out at his November funeral.
