The man accused of driving a van into a crowd of people near a north London mosque has denied he was behind the wheel during the attack.
Darren Osborne, 48, told Woolwich Crown Court a "guy called Dave" was driving during the incident on 19 June 2017.
Earlier, evidence from the prosecution alleged Mr Osborne told police on the day of his arrest he was "flying solo".
He is accused of mowing down people in Finsbury Park, killing Makram Ali, 51, and injuring nine others.
Mr Osborne, from Cardiff, denies charges of murder and attempted murder.
Defence barrister Lisa Wilding QC asked Mr Osborne: "Were you the driver of the van?" to which he replied: "No".
Ms Wilding said: "Did you know who was the driver of the van?" and he replied: "A guy called Dave".
Taking to the witness box, Mr Osborne said he had met "Dave" at the Pick and Shovel pub in Treforest, South Wales, in early April or March last year.
Earlier, the court heard evidence on whether Mr Osborne acted with accomplices - namely two men, known only as "Dave" and "Terry Jones".
Concluding the prosecution case, Jonathan Rees QC said Mr Osborne told the Metropolitan Police on the day of the attack that he was acting alone.
He read a statement from Det Con Paul Dring, who interviewed Mr Osborne as he was under armed guard at University College Hospital, on the day of the attack.
DC Dring said he asked Ms Osborne: "In terms of what happened today, is there anyone else involved?" to which the defendant allegedly replied "no".
The court heard that at the end of the interview, DC Dring asked: "Finally from me, is there anything at all that you know about that could harm anyone?"
Mr Osborne replied "no", and after a pause added: "I'm flying solo", the court heard.
