But sources in the BJP said that the RSS has played a behind the scene role in Jaswant's exit.
In fact, before starting off for Shimla, BJP president Rajnath Singh met RSS chief Mohan Bhagwat and discussed some of the recent acts of 'indiscipline' committed by Jaswant Singh, including on his latest book, 'Jinnah - India-Partition-Independence'.
Senior BJP leader and political adviser to Rajnath Singh, Prabhat Jha told ANI over phone from Shimla that Jaswant Singh was expelled on grounds of indiscipline.
"We have lost ground in the elections. He was such a senior parliamentarian, a member of the core committee and parliament. He should have maintained discipline," Jha said.
When asked whether the RSS had played a role in Singh expulsion, Jha said, "It is the decision of BJP."
Earlier in the day, the BJP parliamentary board expelled Singh following the release of his book, which eulogises Jinnah and demeans Sardar Patel and Jawaharlal Nehru.
