After the poll debacle in Bihar, Congress on Saturday accused the Election Commission of India (ECI) of being one-sided and questioned the electoral process.

The allegations were levelled by senior party leader KC Venugopal after a meeting was held at party president Mallikarjun Kharge's residence in New Delhi.

Venugopal said that they are collecting data and conducting a thorough analysis and will present 'concrete proof' within 1 or 2 weeks.

"The result which has come from Bihar is unbelievable for all of us... Our alliance parties do not believe it... We are collecting data and conducting a thorough analysis, and within 1 to 2 weeks, we will provide concrete proof... The Election Commission is totally one-sided... This process is questionable," he said.

The meeting at Kharge's residence was attended by senior party leaders, including Rahul Gandhi, who led the poll campaign from the front in Bihar.
