Addressing a wel attended party rally at the Shankumugham Beach here, Modi wanted the people to introspect whether they want to be ruled alternately by the Congress-led UDF and the CPI(M)-led LDF.
Holding that there was no qualitative difference between the two rival fronts, he said for the last several decades they had been "hoodwinking" the people by engaging themselves in a shadow boxing.
He alleged the Communist Party did not believe in democracy and wanted instability for survival whether in Kerala or outside.
Under the rule of these coalitions, Kerala had wasted its huge potential in areas like tourism, holistic medicine and service sectors, he said.
"Why do lakhs of youth from this state go abroad in search of jobs, leaving their parents and beloved ones behind ? It is time that you introspected who is responsible for the plight. These two fronts looted this sacred land. How can we go forward without bringing about a change to this situation ?" he said.
