The prime objective of the campaign would be to expose the mindset of a former BJP leader, who was also a minister, the statement said.

State and district level party leaders would organise sit-ins across towns and cities against Singh for making comments against Patel, who played a key role in the freedom movement in Gujarat and across the country.

Singh in his book has said that Jinnah was 'demonised' in India, while part of the blame for the country's partition should also go to the country's first prime minister Jawaharlal Nehru and first home minister Sardar Vallabhbhai Patel. 'Jinnah: India, Partition, Independence' has already been banned in Gujarat.
