"Isn't Modi and now BJP's slogan of Congress Mukt Bharat Fascist? For would all other non-BJP, non-communal political parties pl respond," Singh said on microblogging site Twitter.
The Congress general secretary, who is also AICC-in-charge for Andhra Pradesh, also hit out at BJP for not talking about its earlier slogan of "Bhay, Bhook and Bharashtachar Mukt Bharat (fear, hunger and corruption free India)".
"BJP's earlier slogan bhay, bhook, bharashtachar mukt Bharat; Modi's slogan Congress Mukt Bharat.Now in Modi's BJP, Bhay Mukt, Bhrashtachar Mukt Bharat no longer an issue.Would the BJP think tank or spokespersons pl respond," Singh said in two other tweets.
The latest attack on Modi comes close on the heels of Congress leaders dubbing the Gujarat Chief Minister as a frog just out of well, national embarrassment, symbol of ignorance and illiteracy and having abrasive hunger for power which has no limits.
Addressing a rally in Hyderabad recently, Modi had invoked the legacy of N T Ramarao urging all non-Congress parties to come together with apparent specific signal to TDP to join the NDA bandwagon.
"Congress party is a burden on this nation. Today. I want to remember NTR when I come here. NTR did service not only to Andhra but the whole of India when he gave boost to anti-Congress politics.It was NTR's efforts that paved the way for formation of a non-Congress government at the Centre.
Another party general secretary Shakeel Ahmed also took potshots at the BJP over its mission '272+' and Modi's reported claim that 25 per cent Muslims in Gujarat had voted for him in the assembly elections.
"First it was 272 seats, then BJP says under Modi we will try to attract Muslims. Wondering whether it is campaign committee or comedy circus?," Ahmed said in a tweet.
Ridiculing the BJP over it, Ahmed said in another tweet, "Even die-hard supporters of BJP are laughing their heads off over party's claim that it will get 272 seats in Lok Sabha elections".
