Cricketer-turned-minister Navjot Singh Sidhu, attacked by critics for his visit to Pakistan for Imran Khan's oath ceremony and a controversial hug shared with the Pakistani army chief, hit back today with a detailed rebuttal. Asserting that his visit was "not about politics" but a warm invite from an old friend, the Punjab minister pointed out that former prime minister Atal Bihari Vajpayee had travelled on the bus to Lahore and Prime Minister Narendra Modi made an unscheduled trip to Lahore in 2015, on his way back from an official visit to Afghanistan.
