UK PM Johnson visits scene where MP was fatally stabbed in terrorist incident

The murder has shocked the nation and prompted calls for a review of security measures for lawmakers carrying out constituency work. Amess, 69 and a member of Prime Minister Boris Johnson’s ruling Conservative Party, died after being stabbed several times at around midday Friday at Belfairs Methodist Church in Leigh-on-Sea, England.A 25-year-old man was arrested on suspicion of murder and a knife was recovered, police said. He is believed to have acted alone.”The early investigation has revealed a potential motivation linked to Islamist extremism,” the Metropolitan Police said in a statement overnight. Two addresses in the London area are being searched, the force said. The man arrested is believed to be a British national with Somali heritage, official sources have told UK news agency PA Media. The UK’s Counter Terrorism Command is leading the investigation into the killing, police said Friday.Johnson: ‘We lost a fine public servant’The country’s political, religious and societal leaders, and its royal family, all condemned Friday’s attack and paid tribute to Amess.Those who knew him described Amess — who was married with five children — as a dedicated local representative, deeply embedded within his community and uninterested in the careerism of national politics. A vigil was held Friday evening at St. Peter’s Catholic Church in Leigh-on-Sea for local people to pay tribute to Amess.”Everyone was just speechless. It was just awful. He was just such a kind, gentle soul, really witty, quite quirky and liked by a lot of people, and it was just shocking. Absolutely shocking,” local resident Melanie Harris told CNN.Amess entered Parliament in 1983, initially representing the Basildon constituency, and had served continuously in the House of Commons since then, making him one of the longest-serving lawmakers in the chamber.Lawmakers from across the political spectrum spoke Friday of their sadness, concern, and anger that another of their colleagues was killed while meeting with constituents. In a statement Friday from Downing Street, Johnson said the MP “was one of the kindest, nicest, most gentle people in politics.””David was a man who believed passionately in this country and in its future,” Johnson said. “We lost today a fine public servant.”Starmer wrote on Twitter: “Horrific and deeply shocking news. Thinking of David, his family and his staff.”Flags outside Parliament were lowered to half staff after Amess’ death.Amess was knighted in 2015 for his political service. He supported Britain’s departure from the European Union, and his main areas of expertise were animal welfare and pro-life issues, according to a biography on his website. He was not considered a controversial politician, and despite the length of his tenure, he was not a widely known political figure in the UK.In a book he wrote last year about being an MP, Amess said Cox’s murder was “totally unexpected” and the event had changed the way MPs interact with members of the public, particularly in relation to constituency surgeries. “These increasing attacks have rather spoilt the great British tradition of the people openly meeting their elected politicians,” he wrote. “I myself have over the years experienced nuisance from the odd member of the general public at my own property. We regularly check our locks.”CNN’s Nada Bashir reported from Leigh-on-Sea and Sharon Braithwaite from London, while Laura Smith-Spark wrote from London.
