An online book of condolence has been set up in memory of Jo Cox.
The Labour Party made the move as tributes poured in from across the world for the Batley and Spen MP - including one from Hillary Clinton in the United States.
Labour leader Jeremy Corbyn, who laid flowers in Birstall, said: “Jo Cox stood for tolerance, justice, peace and human rights. We must come together as a country and face down hatred and intolerance in our society.
“We send Jo’s family, her two young children and her husband Brendan our deepest condolences and love. They are in the hearts of all of us.
“We have established an online book of condolences so that Labour members and supporters can send their own messages of condolence and express their thoughts at this troubling time.”

A book of condolence is also available at Birstall Parish Church.
Mrs Clinton expressed her condolences in a statement, saying: “We must honour Jo Cox - by rejecting bigotry in all its forms.”
