"Congress' main fight in the 2014 Lok Sabha polls will be with RSS. BJP is just a mask," Ramesh said while addressing a rally at Dumariyaganj in Siddharthnagar district.
There were six to seven states where the contest is with RSS, he said.
Ramesh alleged that BJP's prime ministerial candidate Narendra Modi and party Uttar Pradesh incharge Amit Shah were sowing seeds of hatred through their rallies.
He alleged that they were showing a dream of development to the people by projecting Gujarat as a model, but there were several social problems in the state.
He said it was up to the people to elect which type of representative they wanted.
A team of the Rural Development Ministry would soon prepare a detailed plan of development of the area, he said.
