LONDON: UPA chairperson Sonia Gandhi and industrialist Ratan Tata were among the world's "50 most influential people" along with German chancellorAngel Merkel, who was ranked No 1, according to a survey by UK-based magazine NewStatesman. 

I think  sonia gandhi is not better politician as the congress present him infront of the people . she is always front of the sucessfull event ,achivements ,award function but when the india is in trouble and when the congress party image down she never comes in front of the camera.so i think in this rating she is not a eligible lady because many great politicians are in this country as Atal bihari Vajpayee .I think this is the matter for review again.
