Nicola Sturgeon to join Kezia Dugdale in vigil for Jo Cox at George Square

Hundreds of people are expected to attend the square alongside the First Minister and Kezia Dugdale.

The service will be held to celebrate the light Jo shone in the world, and to show that her message of solidarity, love and empathy will always win.

A second vigil will take place on Lothian Road in Edinburgh at 6.30pm. 

As news of MP Jo Cox's death spread around the world, tributes from international public figures flooded in.

Hillary Clinton, the presumptive Democratic presidential nominee, led the tributes saying she was horrified by the "assassination" and calling Mrs Cox a "rising star".

She referenced Mrs Cox's maiden speech which celebrated the diversity of her constituency.

"It is cruel and terrible that her life was cut short by a violent act of political intolerance," Mrs Clinton said.

"It is critical that the United States and Britain, two of the world's oldest and greatest democracies, stand together against hatred and violence.

"This is how we must honour Jo Cox - by rejecting bigotry in all its forms, and instead embracing, as she always did, everything that binds us together."

Canadian prime minister Justin Trudeau tweeted a message in French and English.

He wrote: "On behalf of our Parliament and all Canadians, I offer my deepest condolences to the family and colleagues of British MP Jo Cox."

Ireland's premier Enda Kenny announced that, in light of the suspension of campaigning by the Leave and Remain groups, he would not be speaking on the EU referendum as planned.

He also tweeted: "What an appalling tragedy. Jo Cox, a mother doing her public duty, her life taken away. My deepest sympathies to her family."

The president of the European Council, Donald Tusk, offered his condolences after a visit to Finland.

He said on Twitter: "Repelled by tragic attack on British MP Jo Cox. My thoughts are with her family and loved ones."

Australian prime minister Malcolm Turnbull said he was "deeply shocked".

He added on Twitter: "Our condolences, prayers and solidarity are with her family & the people of the UK."

The Twitter account of the Malala Fund, the organisation led by Pakistani girls' rights activist Malala Yousafzai, who survived being shot in the head by terrorists, retweeted a comment from her father.

Ziauddin Yousafzai tweeted a link to Mrs Cox's speech calling on Britain to help the victims of the war in Syria and said: "May her soul rest in peace. Jo Cox left behind a legacy of love,respect &peace."

US secretary of state John Kerry and Danish prime minister Lars Lokke Rasmussen also offered condolences to Mrs Cox's friends and family.

Mr Kerry, who was travelling in northern Europe on Thursday, said the attack was "an assault on everybody who cares about and has faith in democracy".

Mr Rasmussen called the killing "a true shock".

It is understood that the Prince of Wales and the Duchess of Cornwall will write privately to the MP's husband, Brendan Cox.

In Glasgow the 26th meeting of the British-Irish Council, hosted by Scotland's First Minister Nicola Sturgeon, began with a minute's silence in memory of Mrs Cox.

Addressing a press conference after the summit, Ms Sturgeon said: "We all want to convey our heartfelt sympathies to Jo's husband, to her two young children, to her wider family and indeed to everyone who loved her.

"As politicians we all value and are deeply committed to the openness and accessibility of elected representatives to the people we serve that is in very many ways the hallmark of our democracy.

"So events like yesterday's, although thankfully very rare, hit all of us as politicians very hard but I think I speak on behalf of all of us when I say that we are all determined, inspired by Jo Cox to rededicate ourselves to the notion of politics and public service as a force for good."

Batley and Spen Labour Party released a statement saying: "Yesterday Batley and Spen Labour Party lost our wonderful friend and MP Jo Cox. She meant the world to us. She was a lovely woman who cared deeply about her family, her community and everyone around her.

"She had an incredible passion for helping people and trying to improve the world at every level, from making Batley station a nicer place for the people who use it to championing the cause of the people of Syria who have suffered so much in recent years.

"She was intelligent, but so down to earth, and anyone who met her for the first time felt like they had known her for years.

"Above all, she was an amazing wife to Brendan and mum to her two children. It is a tragedy that they will have to grow up without their lovely mum."
