Day after stunning success of ‘Mission Shakti’, Prime Minister Narendra Modi launched his poll campaign at a mega rally in Uttar Pradesh’s politically-sensitive Meerut on Thursday. In a powerful speech, the Prime Minister launched a scathing attack on the Opposition for demanding the proof of the Balakot air strike. “Kya aapko saboot chahiye ya aapko sapoot chahiye (Do you want proof or do you want the good son of the soil),” asked PM Modi in a sharp swipe at the Opposition leaders.
