Mr Clarke said the investigation of the material seized by police was likely to take months.
In a highly unusual development, Mr Clarke went into significant detail about the evidence so far uncovered by police inquiries. These included:
# 69 searches of houses, flats and business premises, vehicles and open spaces
# Searches had found more than 400 computers, 200 mobile telephones and 8,000 computer media items such as memory sticks, CDs and DVDs
# Police experts have removed 6,000 gigabytes of data from the seized computers
# Bomb making equipment, including chemicals and electrical components seized, police say
# A number of video recordings recovered.
At the news conference, Susan Hemming, head of the Crown Prosecution Service Counter Terrorism Division, said she had been working with Scotland Yard officers for the past eight days.
"We have been carefully examining and assessing the evidence against each individual with the assistance of anti-terrorist officers in order to come to charging decisions at the earliest practicable opportunity."
She added that the position of the 11 people still in custody would be "assessed on a regular basis".
"We cannot yet make a decision about whether further charges will follow or if a further application for detention will be made on Wednesday, as the evidential picture is continuously developing."
