In an apparent reference to Narendra Modi's attack on Congress as "termites" and him as a "night watchman" at the BJP National Council meeting in Delhi on Sunday, he said the party hurled the "choicest abuses" against the Congress leadership and made it clear he would not reply to them in "that language".
Winding up the discussion on the motion of thanks on the President's address, Singh spoke at length on various issues including economy, keeping India's options open on the US resolution against Sri Lankan at the UNHCR vote, ties with Pakistan and the situation in Maldives.
Reserving his reposte for BJP, the Prime Minister said "You used choicest abuses against us. It is not my intention to reply in that language because our performance is the best judge."
Employing Urdu and Hindi couplets and proverb deftly, the usually-soft spoken Singh took pot shots at L K Advani, saying the BJP lost the 2004 polls after its "India Shining" campaign and faced defeat against in 2009 when they pitted "iron man" against the "lamb that Manmohan Singh is".
"Jo garajte hain, woh baraste nahi (Thunderous clouds do not bring showers)," he said taking a dig at BJP's use of strong words of criticsm.
