The husband of murdered MP Jo Cox has issued a heartbreaking statement following her death in Birstall .
Brendan Cox said his wife 'believed in a better world' and would want everyone to unite to 'fight the hatred that killed her'.
He said: "Today is the beginning of a new chapter in our lives. More difficult, more painful, less joyful, less full of love.
"I and Jo’s friends and family are going to work every moment of our lives to love and nurture our kids and to fight against the hate that killed Jo.
"Jo believed in a better world and she fought for it every day of her life with an energy, and a zest for life that would exhaust most people.
"She would have wanted two things above all else to happen now, one that our precious children are bathed in love and two, that we all unite to fight against the hatred that killed her. Hate doesn’t have a creed, race or religion, it is poisonous.
"Jo would have no regrets about her life, she lived every day of it to the full."
Prime Minister David Cameron said the Labour MP had a big heart and that people would be 'very, very sad' about the tragedy.
He said: "We've lost a great star.
"She was a very strong campaigning MP. She had a great track record of caring about refugees and had taken a big interest in how we can look after Syrian refugees and do the right thing in our world.

"She was a star for her constituents, a star in Parliament and a star right across the House."
Labour leader Jeremy Corbyn said: "Jo Cox died doing her public duty at the heart of our democracy, listening to and representing the people she was elected to serve.
"In the coming days, there will be questions to answer about how and why she died. But for now all our thoughts are with Jo's husband Brendan and their two young children. They will grow up without their Mum, but can be immensely proud of what she did, what she achieved and what she stood for.
