New Delhi: Congress President and UPA Chairperson Sonia Gandhi launched the Central government's historic Food Security Scheme in New Delhi on Tuesday. The launch of the programme coincides with the birth anniversary of late Prime Minister Rajiv Gandhi. 'Today is the birth anniversary of Sh. Rajiv Gandhi. He had a dream; he had vision; he had an aim -- a strong, happy and modern India. He had, therefore, travelled across the country, visited every nook and corner and interacted with the poor people to closely understand their problems. Throughout his life, he put in all possible efforts to bring in positive changes in the lives of the poor. His farsighted vision for nation building and for the welfare of common people will continue to inspire us' said Sonia Gandhi..
