The Prime Minister, who did not take the name of Modi and instead referred to him as BJP leader from Gujarat and "big BJP leader", said there were "several question marks" over the Gujarat model of development which the BJP Prime Ministerial candidate has been flagging in many of his election speeches.
"The BJP leader from Gujarat is always talking about the Gujarat model of development. But it is well known that several question marks were raised over the Gujarat model of development.
Slamming the BJP, Singh said it has brought down the standard of political discourse and asked the people to "think seriously" what the party which believes in "demeaning others" will do to the country.
Taking potshots at Modi, he said the Gujarat leader had made "several goof-ups in matters relating to history".
"This showed what kind of a man he is," Singh said in the hard-hitting speech.
In its enthusiasm, BJP was only interested in levelling personal attacks on leaders from rival parties, he said.
