Kim Leadbeater, the sister of murdered Labour MP Jo Cox, has reflected on the decade since her sister's killing, describing it as a period of both profound loss and significant change in British politics. In an interview marking the 10th anniversary of the tragedy, Leadbeater spoke about the enduring impact of her sister's death and the lessons learned.
A Decade of Grief and Growth
Leadbeater, who herself became a Labour MP in 2021, said the past 10 years have been a journey of navigating personal grief while witnessing a shift in the political landscape. She noted that Jo Cox's murder, which occurred during the 2016 EU referendum campaign, was a stark reminder of the dangers of political polarization.
“There are things worse than losing your sister,” Leadbeater said, referencing the title of a new documentary about her sister's legacy. She emphasized that while the pain of losing Jo remains, the outpouring of support and the continued fight for the causes Jo championed—such as refugees and international development—have provided solace.
Political Climate Then and Now
Leadbeater contrasted the political climate of 2016 with today, noting that while some aspects have improved, others remain concerning. She pointed to the rise in online abuse and threats against politicians, a trend that has worsened in recent years. However, she also highlighted the increased awareness of mental health and the importance of community cohesion.
“Jo’s murder was a wake-up call for many about the toxicity in politics,” Leadbeater said. “But we’ve also seen incredible acts of kindness and solidarity, which give me hope.”
Legacy and Remembrance
The Jo Cox Foundation, established in her memory, continues to work on issues including loneliness, community engagement, and social justice. Leadbeater remains actively involved, ensuring her sister's legacy endures. A series of events are planned to mark the anniversary, including a memorial service and community projects.
Leadbeater also reflected on her own journey into politics, which she said was partly inspired by Jo’s example. “I never wanted to be a politician, but I felt a duty to carry on her work,” she explained. “It’s been challenging, but also rewarding.”
As the nation remembers Jo Cox, Leadbeater’s message is one of resilience and hope. “We can’t let hatred win,” she said. “We must continue to build a world where difference is celebrated, not feared.”
