Uttar Pradesh Chief Minister Mayawati tops the list of chief ministers in the five election-bound states with maximum assets worth Rs 87 crore and 46 per cent of her ministers have criminal cases pending against them, according to data released Tuesday by an NGO and a non-political organisation.

"RTI responses from five states showed Mayawati has the highest assets at Rs 87 crore," said the data. "Chief Minister of Manipur Okram Ibobi Singh has the lowest assets at just Rs 6 lakh."

Around one-third of a total of 100 ministers in the five states of Uttar Pradesh, Uttarakhand, Punjab, Goa and Manipur have self-declared pending criminal charges, showed the data.

NGO National Election Watch and non-political organisation Association for Democratic Reforms (ADR) released the data on the basis of a study linked to RTI responses by state governments.

Punjab's Parkash Singh Badal is the only chief minister who has got a criminal case, related to cheating and forgery, against him, said the study. He has assets worth Rs 9 crore, according to the study.
