New Delhi: Ahead of Prime Minister Narendra Modi's "did your nana-nani lay water pipes?" crack at Congress President Rahul Gandhi, the veteran leader of the grand old party Kapil Sibal took to micro blogging website Twitter for counter attacking at the PM. He claiming that "Nehruji laid the foundation of modern industrial India" in his scathing tweet.

Earlier, PM Modi launched a scornful words of war on the ruling Congress party while addressing a rally in Chhattisgarh. While Congress President has accused the BJP of forged promises and corruption, PM Modi questioned whether Rahul's grandparents layout water pipelines in the nation.

Senior leader Sibal also accused the patriarchs of the Bharatiya Janata Party of having collaborated with the British during colonial regime.

"Ask how you got drinking water at the platform when you were young. Nehruji laid the foundation of a modern industrial India, but your party's Nana Nani's Dada Dadi's collaborated with the British," Sibal alleged in a tweet.

In addition at the election rally in Ambikapur, PM Modi also asked if Congress had anyone outside the Gandhi family as President and countering this, another veteran leader P Chidambaram reminded the PM of Congress party's legacy and named a number of non-Gandhi family presidents in the party.

"To jog PM Modi's memory: among the Congress Presidents since 1947 were Acharya Kripalani, Pattabhi Sitaramayya, Purushottamdas Tandon, U N Dhebar, Sanjiva Reddy, Sanjivaiah, Kamaraj, Nijalingappa, C Subramanian, Jagjivan Ram, Shankar Dayal Sharma, D K Barooah, Brahmananda Reddy, P V Narasimha Rao and Sitaram Kesri (sic)," Chidambaram cornered PM Modi .
