NEW DELHI: Prime Minister Narendra Modi on Sunday declared that he “does not see any challenge (for BJP) from any quarter” in 2019 as he tore into the opposition and mounted a full-scale attack on Congress chief Rahul Gandhi as well as the opposition's efforts to stitch together a "grand alliance" against the BJP for the 2019 Lok Sabha elections.Delivering his valedictory address to the party’s national executive in Delhi, Modi set the tone for the upcoming assembly and parliamentary elections.Modi said “the compulsion of opposition parties to forge an alliance against BJP is the success of the party,” according to law minister Ravi Shankar Prasad, who quoted the PM at a press conference on Sunday.Explaining the opposition’s “compulsion”, Modi said, “Today opposition unity (Mahagathbandhan) is being talked about, but parties who do not see eye to eye, are trying to come together. Mahagathbandhan is clueless about leadership, unclear on strategy and nurtures corrupt intent (netritwa ka thikana nahin, niti aspasth, niyat bhrasth),” according to Prasad.Without naming Congress president Rahul Gandhi, Modi mounted a scathing attack on him. “Nobody is ready to accept Congress’ leadership ... even smaller parties refuse to accept ... some of them consider the Congress leadership a liability. Within Congress too, the situation is such that there is a reluctance in accepting his leadership ...” Prasad said quoting Modi.Taking the party line that was set by BJP chief Amit Shah at the meet on Saturday, Modi said, Congress had failed as a ruling party as well as a party in opposition, since it has not been able to raise any valid issue and has only relied on lies and falsehood against the (Modi) government, Prasad told the media.“The comparison should be between their 48 years (Congress rule) and 48 months of our (Modi) government ... should seek questions on policies, which will give us a chance to question Congress about its 48 years,” Modi told the party as it gets into the campaign mode.Slamming Congress on the issue of eradicating poverty and serving the poor, Modi said, “They (Congress regimes) said we will do away with poverty ... garibi hatao (end poverty) ... so they nationalised institutions ... then they went for reforms ... how did it help the poor.” Modi highlighted the welfare schemes of the present government that, he said, have benefited the poor and impacted their lives.The PM also launched BJP’s new slogan before the polls “Ajeya Bharat, Atal BJP” that Prasad elaborated as “a victorious India that cannot be subjugated by anyone and a party which is committed to its principles,” as the party goes into campaign mode.
