The inflow of migrants into Delhi needs to be stopped to solve the problems of the capital, BJP leader Vijay Goel said in the Rajya Sabha as the upper house debated the Delhi budget."Every day more migrants come to Delhi... Most of them are from Bihar and Uttar Pradesh. They come here because they don't have employment opportunities in their states," Goel said."These migrants settle in slums, which later become unauthorised colonies. If we have to solve the problems of Delhi, we need to stop this inflow of migrants," he said.Goel also suggested opening branches of Delhi University colleges in other states to stop migrant inflow."Students come here every year because there aren't any good colleges in their states. We can open branches of colleges in other states to stop this inflow," said Goel.The Lok Sabha Wednesday passed the budget for Delhi, which is at present under President's rule.
