Home Minister Sushil Kumar Shinde today said that there is no need for Narendra Modi, the BJP's prime ministerial candidate, to be guarded by the Special Protection Group or SPG, which protects the Prime Minister and other VVIP politicians like Congress president Sonia Gandhi. Mr Modi's security has become a boldface controversy after a series of bombs exploded ahead of his rally in Patna on Sunday, killing six people and injuring 83.
