Claiming that Sushma Swaraj has been targeted under a "political game" to oust her from BJP, Shiv Sena today said it is imperative for Prime Minister Narendra Modi to step in and order an investigation to know who is so keen on "maligning" her "clean" reputation.

Sena, which has come out in support of the External Affairs Minister in the row over helping scam-tainted former
IPL Commissioner Lalit Modi obtain British travel papers, said Congress was "lifeless" and its reaction did not mean much but "who is trying to give flight to its wings".
