New Delhi, Aug 23 - Expelled Bharatiya Janata Party (BJP) leader Jaswant Singh Sunday said he never knew the party was so 'narrow minded' to unceremoniously sack him for writing a book.

He said the contention in his controversial book, 'Jinnah -- India, Partition, Independence', that the founder of Pakistan was a 'great man' and had been 'demonised' in India was based on facts, and wondered that it should upset his party leadership.

'I didn't think the party is so narrow-minded...so nervous about Jinnah and Patel and to get so riled at what I have written. I have a feeling, which I voiced also, that perhaps my former colleagues had not really read the book when they passed the sentence,' he told Karan Thapar on 'Devil's Advocate' programme on CNN-IBN television channel.

Singh, who has handled external affairs, defence and finance portfolios in the BJP-led National Democratic Alliance government, was unhappy that the party did not distinguish between Jinnah's personal attributes as a human being and his politics while taking a decision to expel him.
