Gandhi said his new responsibility was a big one and told party workers that he will treat all of them equally, will learn from their experiences but will only play a judge.
"It is a big responsibility. I will work for everybody from today but I will play the judge and not the lawyer," he said.
He said the time has come to question the "centralised, unaccountable system and decision making must shift from Delhi to the panchayats".
"Why do a handful of people control the entire political space," he asked, adding that "people with little understanding were sitting at high positions".
"We don't need better systems, we need a complete transformation in the system, we need 40-50 leaders at the national level (anyone of whom can be prime minister) and seven to 10 at the state level (for chief minister)," he said.
