Navjot Singh Sidhu came under fire over his appearance at the opening ceremony of the Kartarpur corridor. The Bharatiya Janata Party launched a salvo at the former Punjab minister for heaping praise on Pakistan Prime Minister Imran Khan. Sidhu had attended the event as an invitee of the Pakistani government. The corridor was opened ahead of the 550th birth anniversary of Guru Nanak, the founder of Sikhism.
