The three-judge panel dismissed Tarrant’s claim that harsh prison conditions and poor mental health had caused him to plead guilty involuntarily in March 2020, concluding there was no evidence he had suffered from a mental impairment that affected his legal judgment.

“He was not suffering from a mental impairment or any other form of mental incapacity which rendered him unable to voluntarily change his pleas to guilty,” the judges wrote in their decision.

The court said the Australian national, now 35, had attempted to mislead judges about his mental state in what it described as “a weak attempt to advance an appeal,” adding that evidence showed he had made an informed and rational decision when he admitted guilt.

Tarrant carried out the attacks in March 2019, driving to two mosques in Christchurch during Friday prayers and opening fire with semiautomatic weapons, killing 51 people and injuring dozens more in New Zealand’s deadliest modern mass shooting.

His guilty pleas a year later spared victims’ families and survivors from a lengthy public trial, which many feared would give him a platform to spread extremist views.The appeal court noted that Tarrant’s bid to challenge those pleas was filed 505 days after the legal deadline, but it proceeded to hear the matter because of its public significance.

During a five-day hearing in February, Tarrant argued that “irrationality” caused by poor mental health had temporarily led him to abandon his white supremacist ideology and plead guilty.

The judges rejected that argument, saying prison staff, mental health professionals and his former lawyers did not support his claims. They also noted that he had accepted the summary of facts presented by police and the sentencing judge, while the evidence against him was overwhelming.

That evidence included video footage of the attack that Tarrant filmed himself and livestreamed online, clearly showing his face, as well as a manifesto outlining his racist ideology that he published under his real name before the shootings.

The ruling also disclosed that Tarrant sought to abandon the appeal shortly after presenting his case in February, but judges refused, saying the matter was of “significant public interest and should be finally determined.”They said he appeared to conclude the hearing was not going in his favor and then attempted to withdraw the case after proceedings ended.

Tarrant was sentenced in August 2020 to life imprisonment without parole, the first such sentence in New Zealand’s history. He remains in Auckland Prison.The judges allowed him to abandon a separate appeal against that sentence, which had been scheduled to be heard later in 2026.

London’s Metropolitan Police said a 45-year-old British man born in Somalia was arrested on suspicion of attempted murder after the late-morning assaults, which left two men aged 76 and 34 hospitalized in stable condition.

Police said the suspect, who also allegedly attempted to stab officers during the arrest, is believed to have been involved in a separate incident earlier the same morning in southeast London in which another person sustained minor injuries.

Metropolitan Police Commissioner Mark Rowley said the suspect had “a history of serious violence and mental health issues,” while counter-terrorism officers were leading the investigation to determine motive and possible links to a broader pattern of attacks targeting Jewish communities.

The incident occurred shortly after 11 a.m. local time when the Shomrim Jewish neighborhood watch group reported that a knife-wielding man was attempting to stab Jewish members of the public in Golders Green, an area with a large Jewish population.

Members of Shomrim helped detain the suspect before police arrived and used a Taser to subdue him. The victims were treated at the scene by Hatzola, a Jewish volunteer ambulance service, before being taken to hospital.King Charles III, currently on a state visit to the United States, said he was “deeply concerned” by the attacks in a statement issued by Buckingham Palace.

Prime Minister Keir Starmer described the stabbings as “appalling” and convened an emergency meeting of senior ministers and officials, saying the government would ensure a swift response from criminal justice agencies.“The government is taking action in relation to security, cohesion, extremism,” Starmer told broadcasters, adding that he would meet officials on Thursday to review security arrangements and legal responses.

The attack follows several recent arson incidents targeting synagogues and Jewish institutions in north London, including fires involving Hatzola ambulances and attacks on synagogues in Kenton and Finchley.Police have arrested 28 people in connection with those incidents and Wednesday’s stabbing since the start of the U.S.-Israeli war on Iran on Feb. 28.

A little-known group believed to be linked to Iran, Harakat Ashab Al-Yamin Al-Islamiya (HAYI), claimed responsibility for the stabbing through an online video cited by SITE Intelligence Group, saying one of its “lone wolves” carried out the attack. The claim has not been independently verified.

Israel’s foreign ministry said the attacks showed Britain was failing to protect its Jewish community.“After attacks on synagogues, Jewish institutions, community ambulances and now Jews targeted in Golders Green, the UK government can no longer claim this is under control,” it said in a post on X.

Chief Rabbi Ephraim Mirvis said the Jewish community remained resilient but demanded stronger action.“Such attacks need to stop now. Zero tolerance that’s what our community wants,” he told reporters.

Monitoring groups in Britain have reported a sharp increase in both antisemitic and Islamophobic incidents since the start of the Israel-Hamas war in Gaza, with tensions further intensified by the broader regional conflict involving Iran.
