Waheed Ali, Sadeer Saleem and Mohammed Shakil deny the charges
The jury in the trial of three men accused of helping the 7 July London bombers has retired to consider its verdicts at Kingston Crown Court.
Waheed Ali, Sadeer Saleem and Mohammed Shakil deny assisting the bombers by scouting for potential targets in London seven months before the attacks.
The defendants, all originally from Leeds, each deny a charge of conspiring to cause an explosion.
A total of 52 people were killed in the attacks on London transport in 2005.
Mr Ali, 25, Mr Saleem, 28, and Mr Shakil, 32, are accused of assisting Mohammad Sidique Khan, Shehzad Tanweer, Jermain Lindsay and Hasib Hussain, in what prosecutors say was a reconnaissance mission for the bombings.
Khan, Tanweer, Lindsay and Hussain blew themselves up in four separate suicide attacks on the London Underground and a bus.
The prosecution alleges the three defendants travelled from Leeds to London with Hussain in December 2004 to conduct a reconnaissance of potential targets.
Lawyers claim the visit was "an essential preparatory step in the plan to bring death and destruction to the heart of the UK".
However, the three defendants have argued their trip was entirely innocent and that it was a "social outing" to allow Mr Ali to visit his sister.
All three earlier told the court they held some extreme Islamist views - including supporting militant groups in Pakistan and Afghanistan.
But they said their opinions fell well short of advocating suicide bombings in the UK.
