how can you say it is good? it is just his political ambition and some hidden agenda playing in the foreign hand... so initially he create good impression by Anna movement... and then his real face come out... he is under some hidden source to stop BJP/Modi... corruption is not the only issue good governance is more necessary for healthy growth...
root of corruption is money reqd to fight the election so unless that source made legal from budget corruption will not go... not even by Janlokpal... it will prove one more corrupt, bias govt agency...
