Silver Line rail project: Criticism mounting in Cong against Tharoor

Shashi Tharoor had also said earlier that in some issues it is necessary to put political differences aside.

Discontent is brewing in the state unit of the Congress party over its Member of Parliament Shashi Tharoor's reluctance to sign a letter prepared by the MPs from the party-led UDF to the Centre against the state government's semi-high speed rail corridor and his open praise of Chief Minister Pinarayi Vijayan for his "investment-friendly" initiatives.

An unfazed Tharoor on Friday said in a tweet that on some issues it is necessary to put political differences aside and share his photo with the CM.
