The Rashtriya Swayamsevak Sangh has said it will not allow the Centre to go ahead with the Sethusamudram ship canal project as it posed a "challenge" to Indian culture.
"The RSS is not prepared to make any compromise on the Centre's move to implement the project as it would be a clear instance of grave injustice to the majority people of India," RSS leader K S Sudarshan said inaugurating two-day regional meeting of the outfit in Kasargod in Kerala
I wonder, what has the canal project got to do with the nation's culture?
