Congressman-turned-BJP Rajya Sabha member Jyotiraditya Scindia on Tuesday termed his former colleagues Kamal Nath and Digvijaya Singh as siblings who "ruined" the state.
Campaigning for November 3 byelections in the state at Biora in Rajgarh and Badnawar in Dhar district, he targeted Mr Nath over transfers of officials.
The Congress rubbished his allegations.
"Bada bhai-chhota bhai (elder brother and younger brother) turned Vallabh Bhawan (state secretariat) into a den of corruption. (Mr) Nath would be described as the world's biggest industrialist, so I thought he would bring industries to the state, but in reality he started a transfer industry," Mr Scindia alleged.
A superintendent of police was transferred five times in six months when Kamal Nath-led Congress government was in power between December 2018 and March 2020, the former Congress leader alleged.
"Liquor and mining businesses also thrived. A minister even complained to the Congress president against him. Bada bhai (Kamal Nath) became chief minister, chhota bhai (Digvijaya Singh) became super CM and in 15 months, they ruined the state," Mr Scindia further said.
Referring to his exit from the Congress alongwith MLAs loyal to him which led to the Nath government's fall, Mr Scindia said for the first time in last 70 years 22 MLAs, including six ministers, resigned for the cause of development.
The state was back on the track of development after Shivraj Singh Chouhan took over as chief minister, he said.
Reacting to Mr Scindia's allegations, state Congress spokesperson Jitu Patwari said transfers made by the Nath government were justified, as it had come to power after 15 years and wanted to change governance.
The allegations of corruption were baseless and the Congress has evidence about Mr Scindia's own questionable land deals, he said.
