Describing his expulsion from BJP as "saddening and regrettable", Jaswant Singh on Wednesday said that he will not appeal against the decision or seek any review though he felt that the party did not follow procedures.
He also made it clear that he did not regret writing the book on Mohammad Ali Jinnah and stood by whatever he has written on the "painful period of history".
A visibly emotional Singh said that he was sad that his 30 years of association with BJP has come to such an end but felt he could have been told not to come to Shimla.
Mr. Singh, a member of Lok Sabha from Darjeeling in West Bengal, said his political life was not over and that he would continue to be a member of Parliament.
"Regret. Why should I regret five years of labour? I have written what is my reading of that painful period of history," he said when asked if he regretted writing the book 'Jinnah - India, Partition, Independence' which led to his expulsion from the party.
"I have committed no sin. None whatsoever against India," he said.
Recalling that he was among those given positions of responsibility in the party by Atal Bihari Vajpayee and L K Advani, Mr. Singh said "I'am of course saddened by the way I have been expelled after having worked for the party with dedication for 30 years. I have served the party to the best of my ability," he said.
