Youth Congress workers today sent a package containing history textbooks to BJP's Prime Ministerial candidate Narendra Modi as a "Diwali gift", claiming it was meant to help him "improve his knowledge" of the subject.

"At a recent rally, Modi wrongly said in his speech that Taxila was a part of Bihar, when it was in fact located in North West Pakistan," Mumbai Pradesh Youth Congress president Ganesh Kumar Yadav told reporters during a function held at Azad Maidan in south Mumbai.

Modi also referred to Chandragupta as a great king of the Gupta dynasty instead of the Maurya dynasty, he added.
