Congress general secretary Priyanka Gandhi Vadra on Sunday said a martyred prime minister's son who walked thousands of kilometres for national unity can never insult the country as the Congress held a nationwide protest against the disqualification of Rahul Gandhi from the Lok Sabha. Priyanka Gandhi was addressing a gathering at Rajghat -- the memorial of Mahatma Gandhi -- here to protest against Rahul Gandhi's conviction in a 2019 defamation case and his subsequent disqualification from the Lok Sabha.?
