A man has admitted being part of a terror plot to cause explosions with convicted Dhiren Barot.
Dhiren Barot was jailed for a bombing plot in the UK and US
Barot, 34, was jailed last year for planning blasts in the UK and US using limousines packed with explosives and a radioactive "dirty" bomb.
Nadeem Tarmohammed, 28, from Willesden, north-west London, pleaded guilty at Woolwich Crown Court.
Five other men earlier pleaded guilty to the same charge, and a seventh man will stand trial later this week.
Tarmohammed pleaded guilty to conspiracy to cause an explosion or explosions likely to endanger life.
Mr Justice Butterfield told the jury who will try the seventh man: "Six defendants with whom you were going to be concerned have now pleaded guilty to one of the offences with which you are concerned.
"However, one defendant remains and it will be your duty to decide whether he is innocent or guilty of the charges he faces.
"The fact that the others pleaded guilty is in no sense an indication that this defendant is guilty."
Pleading guilty to the same charge are Junade Feroze, 31, of Blackburn, Lancashire; Mohammed Zia Ul Haq, 28, of Paddington, west London; Abdul Aziz Jalil, 34, of Luton, Bedfordshire; Omar Abdul Rehman, 23, of Bushey, Hertfordshire; and Mohammed Naveed Bhatti, 27, of Harrow, north-west London.
Qaisar Shaffi, 28, of Willesden, north-west London, has pleaded not guilty to the same count, and to charges of conspiracy to murder and possessing a record of information for terrorist purposes, namely an extract from the Terrorist Handbook.
The prosecution is expected to open its case on Wednesday. All the defendants have been remanded in custody.
