The Congress appeared remarkably unperturbed on a day when it lost 12 of 17 MLAs in Meghalaya to the Trinamool Congress, ceding the position of the state's main opposition, as it capped a strategy meeting in Delhi on Thursday with a pledge to uphold unity among opponents of the ruling BJP. "Under the leadership of Sonia Gandhi, we discussed the coming parliament session. We have to raise a lot of issues in parliament. On 29th, we will raise the MSP (Minimum Support Price) and farmers' issue," senior Congress leader Mallikarjun Kharge said in a media briefing.
