Public money is being spent on advertisement campaigns by the ruling BJP, he alleged and added that the word 'development' was being "misused" by the saffron party.
"Money is being spent on 3D campaigning, internet campaigning and unnecessary advertisements," Keshubhai alleged in his blog.
He was referring to Modi's speech, which was recently telecast on specially erected screens in Ahmedabad, Vadodara, Rajkot and Surat with the help of 3D holographic technology and satellite link-ups.
