Weeks 12 - 14: 2 April - 20 April 2007
Wednesday 11 April: Suspect's claim 'is amazing'
Expert Hans Michels says Muktar Ibrahim's story of detonating 2kg (4.5lb) of main charge to check no-one would be hurt was "amazing".
He says the alleged 21 July bomber must have been "very, very sure" that a device he claimed to have tested in a flat would not explode.
Prof Michels told Woolwich Crown Court the devices used on 21 July, 2005 were not capable of exploding.
Friday 13 April: Delays harm criminal justice, says judge
The judge in the 21 July trial criticises delays in the evidence, saying they have shown the criminal justice system in a "very poor light".
Mr Justice Fulford tells the jury at Woolwich Crown Court that a defence expert would not be able to continue giving evidence because the prosecution need more time to consider scientific evidence.
Tuesday 17 April: Tower block booby trap
Manfo Asiedu tells the court he may have saved a tower block of people from being blown up. The 34-year-old says he dismantled a booby-trapped sideboard at the alleged "bomb factory".
His defence barrister, Stephen Kamlish QC, said in doing so he was possibly responsible for "saving the block and all the people in it".
Wednesday 18 April: Suspect realises suicide plan
Manfo Asiedu breaks down in court as he tells the jury about the moment he realised that Mukhtar Ibrahim's alleged plan was to turn all of the men into suicide bombers.
He explains learning the devices' purpose in a demonstration of how to detonate the alleged bombs.
Thursday 19 April: Suspect 'dismantled sideboard bomb'
Manfo Asiedu tells the court how he dismantled a booby-trapped sideboard.
Wearing purple gloves, he demonstrated to Woolwich Crown Court how he says he opened the door and pulled out the battery.
Friday 20 April: Lying in court claim
Manfo Asiedu tells the court that his co-accused Mukhtar Ibrahim told him to lie in the trial because it was not an Islamic court.
He told the trial that he felt it would not be proper to swear on the Koran to tell the truth - and then to do the opposite.
