Google has urged its users in the U.K. to donate to the memorial fund of assassinated British politician Jo Cox.
Cox, a prominent advocate for refugees and supporter of the U.K.’s membership in the EU, was killed Thursday in her West Yorkshire constituency. A man with suspected far-right ties, Thomas Mair, stands accused of her murder, and her widower, Brendan Cox, said her death was politically motivated.
When Mair appeared in court for the first time, he gave his name as “death to traitors, freedom for Britain.”

In a Wednesday post linked to directly from its homepage, Google noted that today would have been the Labour politician’s birthday.
“We’d like to honor and remember Jo Cox MP, who dedicated her life to the belief that there is more that unites us than divides us,” the post read, before urging people to make a donation to her memorial fund.
At the time of writing, the fund had raised over £1.25 million ($1.84 million) in four days, with the current target being £1.5 million.
The proceeds will be used to establish a foundation, with the causes to be “chosen and announced by Jo’s family in line with Jo’s passions.” These may include “women’s empowerment, refugee support and fighting poverty.”
Memorial events for Cox are also scheduled to take place on Wednesday around the world, with the hashtag “#moreincommon”—a reference to Cox’s first parliamentary speech, in which she said: “We are far more united and have far more in common than that which divides us.”

The U.K. referendum on EU membership will take place Thursday. According to recent polling, the likelihood or otherwise of British exit, or “Brexit,” remains too close to call.
Before Cox’s murder, the “Leave” side was gaining a lead in the polls.
