With just a week to go for the trust vote, there is yet another setback for the UPA. The Telengana Rashtra Samiti has said it will not go with the government. The Congress was banking on the three MPs of the Telengana Rashtra Samiti and on Tuesday, party chief K Chandrasekhar Rao told NDTV that he had spoken to UP Chief Minister Mayawati and told her that he is willing to work with her for a common strategy to topple the government.
