The photograph shows Patel with Modi at a function. BJP alleged that it was an attempt by Patel to take "advantage of the popular appeal" of the BJP's Prime Ministerial candidate.
The book, titled 'Vikasnama' (story of development), was published by Citizen Sports Society, Gondia. Edited by Rajesh Khandelwal, it was brought out on the occasion of Patel's birthday on February 17, 2014.
Apart from articles on Patel, the NCP candidate from BhandaraGondia Lok Sabha constituency, the book contains photographs of him with political leaders and industrialists.
According to the complaint, filed by BJP's Shrikant Bhartiya with the state election authorities, Patel is attempting to cash in on Modi's popularity and mislead the voters.
However, NCP leader Ashok Gupta termed it as a non-issue, pointing out that the book contains photographs of Patel with several other leaders. Gupta also said that the book was published before the model code of conduct came into force.
