The meeting assumes significance as a leading news channel quoted sources as saying that the RSS leaders want to make sure there are no hurdles and no one is miffed within the BJP.
With less than 24 hours to go for the declaration of results, the BJP leadership has indicated that the veterans may have to settle for roles assigned to them by the party.
The BJP president, who met Modi in Gandhinagar on Wednesday along with senior party leaders Arun Jaitley and Nitin Gadkari, has said that top leaders of the party will meet and decide the roles of veterans in the saffron camp including former deputy prime minister Lal Krishna Advani after holding talks with them.
Advani, who was deputy prime minister in the previous NDA government, with his vast experience and stature was reportedly not keen on any role in Modi Cabinet.
Talking to reporters after the meeting on Wednesday, the BJP president refused to divulge Advani's role or any other issue.
"He is our senior leader. Any decision about him will be taken after consulting everyone," he said, adding the decision on the next Gujarat Chief Minister will also be taken at the parliamentary board meeting.
There were talks of Advani being offered the post of NDA Parliamentary Party leader or Speaker of the next Lok Sabha.
The party will also have to decide on the part to be played by another veteran Murli Manohar Joshi, a former BJP president, who was reportedly unhappy when he was shifted from Varanasi to Kanpur to pave the way for Modi to contest the seat.
The BJP’s parliamentary board will meet in the national capital on May 17, a day after declaration of results of 16th Lok Sabha elections.
"I have told Narendra Modi to come to Delhi on 17th. I will convene the Parliamentary Board meeting on that date to decide the earliest date to hold BJP parliamentary party meet to formally elect Modi as our leader," Rajnath Singh told reporters in the national capital on Wednesday night after a three-hour meeting with the party's core group leaders at Modi's Ahmedabad residence.
The meeting of the parliamentary board, BJP's highest decision-making forum, will also decide what role party senior leaders will play in the next government, Rajnath said and denied that there is any rift among the party leaders on the issue.
