Shimla, Aug 19 - The Bharatiya Janata Party (BJP) Wednesday expelled senior leader Jaswant Singh from the primary membership of the party two days after the release of his book praising Mohammad Ali Jinnah, the founder of Pakistan.

BJP president Rajnath Singh told reporters here that the party's parliamentary board decided to expel the former external affairs minister from the primary membership of the party.

'Yesterday, I issued a statement about the BJP dissociating itself from Jaswant Singh's views. The party discussed the matter at the chintan baithak (introspection session) and it was decided to expel him,' Rajnath Singh said.
