New Delhi, May 7 - CBI has told the Supreme Court that the trial of BJP leader L K Advani in the Ayodhya demolition case has to be carried on without dropping the conspiracy charge against him as the razing down of the medieval monument was part of a "single larger conspiracy".

The agency, in its recent affidavit, opposed the separation of trial of eight accused leaders -- Advani, Murli Manohar Joshi, Uma Bharti, Vinay Katiyar, Ashok Singhal, Giriraj Kishore, Vishnu Hari Dalmiya and Sadhvi Rithambara -- from 41 others, mainly kar sevaks, allegedly involved in the demolition of the disputed structure on December 6, 1992.

It said separation of the trial, which has found favour with the trial court and the Allahabad High Court, is "totally erroneous".

CBI has challenged the May 20, 2010, order of the High Court dismissing its plea against dropping of the conspiracy charge against Advani and also upholding separation of his trial from those charged with actual demolition and assault on mediapersons.

CBI said "Thus in the interest of justice, it is just and proper that all the accused involved in the criminal conspiracy to demolish the structure performed various acts to achieve the objects of the said conspiracy but either not being charged for all the offences like 120 B (criminal conspiracy), 295 (injuring or defiling place of worship with intent to insult a religion), 295 A (deliberate and malicious acts intended to outrage religious feelings) or not facing trial at all for the offences on account of dropping of the proceedings are tried in court of Special Judge at Lucknow".

The agency said the eight leader named in the second FIR, including Advani, "made provocative slogans from the manch causing the assembly to turn unlawful, resulting in rioting and storming of the structure by the kar sevaks".

"As and when the domes fell, the accused leaders and others on the manch celebrated the same by clapping, hugging each other and distributed sweets etc on the manch which was at a visible distance of about 175 meters from the disputed structure," CBI said.

"The assault on mediapersons who were videographing or taking photographs when the demolition was going on and provocative slogans made from the manch is part of the conspiracy," it added.
