 "With Modi in mind, PM slams BJP for use of \"bad\" language")
He also slammed the Raman Singh-led BJP government in Chattisgarh for failing to curb naxalism, stressing that the fruits of development have not reached the areas where the writ of the naxals runs large.
Singh also attacked the state government for failing to provide sufficient security to Congress leaders who were killed in a massive naxal attack in May this year.

"We should criticise the opposition parties and their policies with which we do not agree. But in this regard, we have to distinguish ourselves, especially from the BJP some of whose leaders use bad language against other party leaders and Chief Ministers," Singh said without naming anyone.
He said Congress workers should refrain from using words which are "insulting" and are against the "dignity " of the party.
Addressing party workers at an indoor stadium here, Singh said it was legitimate for political parties to aim to come to power.
"But to achieve the goal, no party should follow the route of cheap publicity...Elections to the state assemblies and the general elections are nearing. Keeping this in mind opposition parties are making various claims. Some senior opposition leaders are saying things which are not based on facts," Singh said.
He also said that on many occasions, "over-excited BJP leaders change history and geography of the country."
"The people of Chhattisgarh and India are aware that parties that talk big are not capable of coming to power...We should alert the people about parties who have communal ideology but are talking about secularism to mislead people," he said.
