GUWAHATI, Sept. 15 -- Prime Minister Narendra Modi on Sunday accused the Congress of encouraging infiltration in Assam, enabling land encroachment, and aligning with an "anti-India" ideology as he credited the BJP's "double-engine" government for development and a tough stand against illegal immigrants. In the last leg of his visit to northeast India, Modi accused the Congress of neglecting the state's development as well as heroes like Lachit Barphukan and Bhupen Hazarika, while saying that the double-engine government was "correcting those mistakes". Modi addressed two separate gatherings in Mangaldai and Numaligarh areas of the Darrang and Golaghat districts of Assam, respectively. He also inaugurated or laid the foundation stones of projects worth Rs.18,530 crore in the health, connectivity and energy sectors. Modi alleged there was a conspiracy to change the demography in India's border areas, calling it "dangerous for national security", adding that the BJP government will not allow illegal immigrants to take hold of the country's resources or take away the rights of farmers and tribespeople. "After the Bharatiya Janata Party/National Democratic Alliance governments came to power, we have been taking action against encroachers and the state government here has started a campaign to free those lands. We won't allow illegal infiltration and attempts to change demographic balance in border areas to happen," Modi said during his 45-minute speech in Mangaldai. "We will not allow anyone to snatch the rights of farmers, youth and Adivasi people... There are conspiracies in the bordering areas to change the demography with the help of intruders. This is dangerous for national security," he added. The Prime Minister arrived in Guwahati from Manipur on Saturday evening, following which he reached Mangaldai on Sunday morning and made his first address. He later left for Numaligarh, where he spoke to a second gathering of around 20,000 people. Speaking in Numaligarh, Modi stressed that during the Congress's rule, citizens were made to "suffer" and were "insulted". "For a long time during the rule of Congress, the poor were made to suffer and were insulted, because the work of Congress was done by appeasing a particular class. They used to get power. But the BJP does not emphasise appeasement, but satisfaction," he added. He said the party "insulted legendary singer Bhupen Hazarika" in an apparent reference to Congress president Mallikarjun Kharge's remarks in 2019. He said that he can tolerate "gaaliyan" (abuses) hurled at him but not at "Bhupen Da". "Mujhe kitne hi gaaliya de, main bhagwan Shiv ka bhakt hoon, saara zehar nigal leta hoon (No matter how much you abuse me, I am a devotee of Lord Shiva, I swallow all the poison). But when someone else is insulted, I cannot tolerate that." When the Centre conferred the Bharat Ratna to Bhupen Hazarika in 2019, Kharge had questioned the decision, demanding the honour for Shivakumara Swami, an iconic Lingayat seer. Recollecting Mangaldai's association with the Assam Agitation (1979-85) against illegal immigrants from Bangladesh, the PM blamed the Congress for failing to listen to the indigenous people. He also accused the Congress of standing with Pakistan. "Congress stands with all such individuals and ideologies which are anti-India. When that party was in power, it used to remain quiet when terror acts bled the country. Now when our armed forces conducted Operation Sindoor, Congress, instead of supporting our army, stood with Pakistan's forces," he added. At the two events, the PM inaugurated and laid foundation stones of several major infrastructure and industrial projects worth over Rs.18,530 crore. The Assam Congress, in a post on X, said that the PM was inaugurating half-finished projects, adding that "the BJP government's is in dire financial strait....
