Six men have pleaded not guilty to allegations of a planned attack on an English Defence League (EDL) march.
The men, from Birmingham, are accused of preparing acts of terrorism between 1 May and 4 July last year.
It is claimed that they prepared an improvised explosive device.
Jewel Uddin, Omar Mohammed Khan, Mohammed Hasseen, Anzal Hussain, Mohammed Saud and Zohaib Ahmed appeared via prison video link at Woolwich Crown Court in London.
Hasseen is also accused of possessing a document or record containing information that may have been useful to a person preparing to perform a terrorism act on 3 July. He denies the charge.
The charges follow a series of arrests by the West Midlands Counter Terrorism Unit.
Uddin, Khan and Hasseen were arrested after a routine stop on the M1 near Sheffield on 30 June last year.
It is alleged that a cache of weapons was found in the Renault Laguna they were travelling in, along with a note addressed to the EDL, which was planning a rally in South Yorkshire that day.
Hussain, Saud and Ahmed were arrested on 4 July.
The six men spoke only to confirm their names and enter their plea of not guilty. A provisional trial date has been set for 7 May.
