The campaign to keep the United Kingdom in the European Union was accused of exploiting the murder of Labour member of Parliament, Jo Cox, for political gain ahead of Thursday’s vote.

Cox was murdered June 16 in her constituency during a vicious attack that shocked the British political system and suspended EU referendum campaigning for two days.

The man charged with Cox’s murder, 42-year-old Thomas Mair, allegedly has connections to far-right and white nationalist organizations. (RELATED: British Member Of Parliament Dies After Being Shot, Stabbed)

“Jo Cox was a friend of mine – and a passionate voice in our campaign to remain in Europe. Her death was an unimaginable tragedy – but we won’t let her voice be silenced,” said Will Straw, campaign director of Britain Stronger, in an email Monday, according to the political website Guido Fawkes.

In an audio recording leaked to Guido Fawkes, Straw detailed how the Remain campaign will spend the final days of the referendum trying to convince the British people to stick with the EU.

“We need to recognise that people have been pulled up short by Jo Cox’s death and it is now time to make a very positive case for why we want to be in the European Union… to call out the other side for what they have done to stir division and resentment in the UK. That is something we must all do… This is what we think is the closing argument of the campaign, reflecting all the arguments that we have been setting out for many months but also the new context that we’re in. What we want to say is people should vote Remain on Thursday for more jobs, lower prices, workers’ rights, stronger public services and a decent, tolerant United Kingdom,” Straw says in the audio clip.

The polls are still close to call, but betting markets are drifting heavily towards a remain vote. Betting company Ladbrokes puts the chances of remain at 76 percent, compared with 24 percent for leave.
