A jury is due to retire today to consider verdicts in the trial of an alleged far right extremist accused of murdering Labour MP Jo Cox.
Thomas Mair, 53, allegedly shot and stabbed the mother-of-two as she arrived at Birstall library in West Yorkshire for a surgery on June 16, a week before the EU referendum.
The defendant, who allegedly shouted "Britain first", had a stash of neo-Nazi material at his home and had collected a dossier on his 41-year-old Remain campaigning MP, the Old Bailey heard.
At the conclusion of the prosecution case, his lawyer Simon Russell Flint QC, called no evidence on behalf of Mair, of Lowood Lane, Birstall.
Addressing the jury, Mr Russell Flint said: "It is you and you alone who have been charged with the responsibility of determining what are the true verdicts on each of the counts on the indictment."
He added: "You and you alone will determine whether Thomas Mair can return to his quiet and solitary existence or will be forever remembered as the man who assassinated Jo Cox."
Mair denies Mrs Cox's murder, possession of a firearm with intent to commit an indictable offence and possession of an offensive weapon - a dagger.
He also pleads not guilty to causing grievous bodily harm with intent to pensioner Bernard Kenny when he tried to stop the attack on Mrs Cox.
The judge, Mr Justice Wilkie, adjourned the case until 10am on Wednesday when he said he would finish summing up expert, medical and forensic evidence before asking the jury to retire to consider its verdicts.
