Kamal Nath's office said it was a courtesy meeting following the party's defeat in Madhya Pradesh.
Sources privy to the development told that at the meeting, the former Madhya Pradesh Congress President discussed about his future role in the party as he currently holds no official position in the party. He was replaced by Jitu Patwari as the party's Madhya Pradesh unit chief following the defeat in the Assembly elections held in November last year.
Kamal Nath's son Nakul Nath's defeat from Chhindwara came as a major setback for his political career as this particular seat was retained by him for over 40 years and he alone represented the Chhindwara Lok Sabha seat nine times.
Kamal Nath's meeting with Sonia Gandhi is also being seen as an attempt to appease the party's top brass, especially Rahul Gandhi, who is said to be upset with him and has maintained distance from him following the Assembly elections.
