Prime Minister Narendra Modi on Saturday inaugurated the month-long 'Kashi Tamil Sangamam' in Varanasi to rediscover, reaffirm and celebrate age-old links between Tamil Nadu and Kashi – two of the country's most essential and ancient seats of learning. The programme is being organised by the Ministry of Education in collaboration with other ministries like culture, textiles, railways, tourism, food processing, information and broadcasting, and the Uttar Pradesh government. Earlier in the day, Modi had inaugurated the first greenfield airport in Arunachal Pradesh. The airport intends to boost connectivity with the North-Eastern region. Modi is also scheduled to address public gatherings and rallies in poll-bound Gujarat, late in the day.
