Spiritual Guru Sri Sri Ravi Shankar begins his U.P anti-corruption yatra today. He will be holding satsangs in various parts of the state in which he would urge people to take an anti-corruption pledge. The yatra assumes significance, as it is being conducted at a time when political parties in UP are gearing up for 2012 assembly elections and Congress is on the backfoot owing a series of scams under UPA II.
