As Rajnath Singh tries to convince senior leader LK Advani to support Gujarat CM Narendra Modi as BJP's PM candidate, Home Minister Sushilkumar Shinde took a dig at the opposition party.

The BJP parliamentary board will soon take a call on who will be the party's prime ministerial candidate for the 2014 Lok Sabha elections, a party leader said on Wednesday.

"Koi bhi Ramu, Shamu aur Damu ka nam le sakte hain (Anyone can name any Ramu, Shamu, Damu)," said Shinde when asked to comment on BJP's plans to anoint Modi as PM candidate.

Just a few days ago Prime Minister Manmohan Singh speaking to reporters after concluding his G20 visit said, "I will be very happy to work under Rahul Gandhi's leadership."

Rahul Gandhi is currently in Rajasthan for a party rally.
