"If Nawaz Sharif does accept the invitation, let's hope Narendra Modi will serve him chicken biryani!" Congress leader Shashi Tharoor today said in an apparent jibe at the BJP's prime minister-designate.

The reference was obviously to Modi's earlier attack on Congress accusing it of serving chicken biryani to visiting Pakistan premier Raja Pervez Ashraf in 2013 when he had come here on a private visit in the midst of the controversy of beheading of an Indian soldier by Pakistani army.

Addressing a rally in Baghpat in the last week of March, Modi had, alluding to the alleged incursions by the Pakistan army and beheading of the Indian soldier in 2013, again said that while all this was happening, the Congress government was serving chicken biryani to the visiting Pakistan premier.

SAARC Heads of State and Government including Pakistan Prime Minister Nawaz Sharif have been invited to Modi's swearing-in as Prime Minister on May 26.
