CPI(M) Polit Bureau member Sitaram Yechury said the party wants a thorough probe into the allegations of corruption as well as the transfer of the officer.
Senior IAS officer Ashok Khemka was transferred in the wake of his decision to probe alleged undervaluation of properties dealt with by Robert Vadra, son-in-law of Congress chief Sonia Gandhi.
"The Haryana government should answer the reason behind the transfer. A proper investigation must be held. Then only only we will be able to know what is true and what is not," he said.
