Tributes have been paid around the world to Labour MP Jo Cox, who died after being shot and stabbed.
The 41-year-old was attacked after holding a constituency surgery in Birstall, West Yorkshire on Thursday.
Among those who honoured Mrs Cox was Hillary Clinton, the US Democratic Party's presidential hopeful, who said: "It is cruel and terrible that her life was cut short."
Mrs Cox's husband said the mother of two had fought for "a better world".
Her attacker is reported to have shouted "put Britain first" at least twice. A 52-year-old man, named locally as Tommy Mair, has been arrested.
Mrs Clinton said it was "critical" Britain and the United States "stand together against hatred and violence".
Another US politician, Gabrielle Giffords, who was the victim of an assassination attempt in 2011, wrote on Twitter that she was "absolutely sickened" by the killing, praising Mrs Cox as "young, courageous, and hardworking. A rising star, mother, and wife".
Tributes have also be paid from across Europe to Mrs Cox, who had campaigned for Britain to remain in the EU.
