After the Shiv Sena supported the Citizenship (Amendment) Bill, which was passed in the Lok Sabha last night, party chief Uddhav Thackeray today made it clear that Sena's support to the bill in the Rajya Sabha is not a given. The party is already in trouble with new Maharashtra ally Congress, with Rahul Gandhi putting out a sharp tweet denouncing supporters of the bill. "We will not give support to the Bill (Citizenship Amendment Bill) unless things are clear. We haven't got answers to questions we asked in Lok Sabha yesterday," said Shiv Sena chief Uddhav Thackeray, who became Chief Minister of Maharashtra last month with support from the Congress and Sharad Pawar's Nationalist Congress Party (NCP).
