Sonia reached Gulbarga on Saturday afternoon and inaugurated ESI hospital just hours before addressing a public rally here.
About two lakh people from different districts like Bidar, Gulbarga, Koppal, Bellary, and others are expected to be at the rally. She had last week addressed a rally in Bihar.
The Congress party is banking on her after she made constitutional intervention for the development of the region and also giving special status to the backward Hyderabad-Karnataka region after amending the Article 371.
Other Congress party members like KPCC President G Parameshwara, Karnataka CM Siddaramaiah, Digvijay Singh are expected to attend the rally.
