Nine terror suspects will appear in court on Tuesday accused of plotting attacks on major London landmarks including the Houses of Parliament, the Stock Exchange and the US embassy.
The suspects, aged between 20 and 29, from Cardiff, London and Stoke-on-Trent, were arrested in a series of counter-terror raids in December 2009.
They all denied conspiring to cause explosions likely to endanger life or damage property when they appeared before a judge at London's Woolwich Crown Court last month.
They also pleaded not guilty to preparing for acts of terrorism.
They are accused of agreeing on targets, discussing materials and methods, carrying out reconnaissance work, attending operational meetings and downloading and researching files "containing practical instruction for a terrorist attack".
Five of the men are also accused of possession of a document "containing information of a kind likely to be useful to a person committing or preparing for an act of terrorism".
The defendants from Cardiff are Gurukanth Desai, 29, of Albert Street, Omar Sharif Latif, 27, of Neville Street, and Abdul Malik Miah, 25, of Ninian Park Road.
The defendants from London are Mohammed Moksudur Rahman Chowdhury, 21, of Stanliff House, Tower Hamlets, and Shah Mohammed Lutfar Rahman, 29, of St Bernard's Road, Newham, both east London.
The defendants from Stoke-on-Trent are Nazam Hussain, 26, of Grove Street, Usman Khan, 20, of Persia Walk, Mohibur Rahman, 27, of North Road, and Abdul Mohammed Shahjahan, 27, of Burmarsh Walk.
They are all due to face trial on January 23.
