"Congress will not have any electoral alliance with any party which had secret understanding with BJP to win Lok Sabha bye-election as happened at an industrial constituency (Howrah LS seat) near Kolkata", Ramesh told reporters here.
"Trinamool Congress is still a regional party, may be it has contested elections in some seats in other states", he said.
Ramesh said Congress will contest the upcoming Lok Sabha elections banking on its achievements and success in the form of Right to Information (RTI) Act, MGNREGA, Forest Rights Act, Right to Education for children between the ages of 6 and 14, National Food Security Act and New Land Acquisition Act "which have been immensely popular".
