Advani said, "Sadhvi Pragya Singh was arrested on the basis of a motorcycle that was used in the Malegaon blast and subsequently she was kept in the police custody for 16 days in illegal detention. Also, ATS had made a ridiculous disclosure by claiming that the sadhvi and her associates were planning to kill some RSS leaders."

"ATS was making information public and this was being used for political advantage by the Congress which is in power at the Centre," he said.

"I have raised the issue with Prime Minister Manmohan Singh which is related to the affidavit of sadhvi in which she has made very serious allegations against ATS", the BJP leader said.

"The people of India will never forgive the UPA Govt for arresting and torturing Sadhvi Pragya Thakur, Advani said.

The comments came just a day after the National Security Advisor spoke to Advani to explain him the details of the ATS investigation in the Malegaon blast.

Advani also appealed voters to "reward" the BJP government in Madhya Pradesh in the upcoming assembly elections in the state and "punish" the Congress-led UPA government at the Centre in the Lok Sabha polls next year.

"I consider the public of this state to be lucky since it will get an opportunity both for rewarding and punishing governments," Advani said at his maiden election meeting for the November 27 assembly polls in the state.

The people of Madhya Pradesh should reward the Shivraj Singh Chouhan government for its excellent work in the assembly elections and punish the Congress-led UPA government in the Lok Sabha polls to be held about six months later, he said.

Advani said he was of the view that the BJP government in MP would not suffer from any anti-incumbency factor.

During the previous assembly elections in Gujarat, the Congress thought that Narendra Modi would be defeated due to the anti-incumbency factor but that did not happen and Modi emerged victorious, he said.

The BJP leader said that in MP there could be some resentment against the party legislators but all that had been taken care of.

He said that there was great strength in democracy and expressed happiness at the fact that the voting percentage was increasing gradually.
