Patil had earlier resigned as Opposition leader last month. His son Sujoy Vikhe Patil successfully contested the recently concluded Lok Sabha elections on a BJP ticket from Ahmednagar. The Congress leader submitted his resignation as an MLA to Assembly Speaker Haribhau Bagade at his office in Maharashtra, an official told PTI.
Three-time Congress MLA from Sillod and former MoS Abdul Sattar also quit, saying he will join the saffron party. Sattar is a close aide of Maharashtra Congress president Ashok Chavan.
Meanwhile, senior BJP minister Girish Bapat handed in his resignation as MLA after he was elected as an MP from Pune constituency.
