In a letter to Chief Justice Ajmal Mian, the former premier challenged the veracity of the papers submitted by the government to the Swiss authorities and alleged the government was involved in ``criminal conspiracy based on theft, forgery and perjury to eliminate the opposition in Pakistan and impose a one-party rule.''

She also alleged that on the basis of these papers, chief of Accountability Bureau Saifur Rehman has asked the Swiss judge to ``indict me, my husband (Asif Zardari) and my mother (Nusrat Bhutto).''

Benazir's letter to the Chief Justice comes two days after reports came that a Swiss judge indicted an agent of Benazir and her husband on charges of corruption, payment of commissions and moneylaundering.

Meanwhile, Saifur Rehman, a close aide of Sharif, has told BBC TV that Benazir would be arrested only after court orders.

Two Pakistani courts have already issued arrest warrants against Benazir and she is currently out on a surety bail of Pakistani Rs one million. Besides this, her moveable and immoveable properties have been frozen and she has been prevented from travelling abroad.

``We will arrest Benazir after the court order,'' Rehman told BBC, adding, ``her cases are being heard in three or four different courts and bailable warrants were issued against her recently.''

He also dismissed Benazir's charges that the present government was carrying a one-sided trial against her and her family members with a political motive.

``It is totally wrong. I have been repeatedly denying it. We have been accused of holding accountability only against Benazir and Zardari,'' he said and added the cell referred at least 100 corruption cases to the courts of which only 10 were against her.

He saidthe government had provided details of alleged corruption of Benazir to the Swiss authorities in October.
