The man accused of murdering Labour MP Jo Cox has opted not to give evidence in his defence.
Thomas Mair allegedly shot and stabbed the mother-of-two as she arrived at Birstall library for a surgery on June 16.
The court heard that Mair shouted "Britain first" during the attack and had neo-Nazi material at his home in West Yorkshire.
They also heard that he had collected a dossier on Cox, a Remain campaigning MP.
At the conclusion of the prosecution case, his lawyer Simon Russell Flint, QC, told the Old Bailey that the defendant would not be going into the witness box. He said he called no evidence on behalf of Mair.
Mair denies Cox's murder, possession of a firearm with intent to commit an indictable offence and possession of an offensive weapon.
He also pleads not guilty to causing grievous bodily harm with intent to pensioner Bernard Kenny when he tried to stop the attack on Cox.
