In a huge setback for the Congress in Telangana, 12 of its MLAs on Thursday met Assembly Speaker P Srinivas Reddy and gave him a representation to merge the Congress Legislature Party with the ruling Telangana Rashtra Samithi. The Congress’s strength in the 119-member House came down to 18 after the party’s Telangana state unit chief Uttam Kumar Reddy tendered his resignation from the Assembly Wednesday after being elected to the Lok Sabha from Nalgonda.
