Ben Carroll is beginning his first full day as Victorian premier, just four months out from the state election.Mr Carroll emerged from a chaotic caucus meeting yesterday as the third Labor leader this term.The 51-year-old has already promised significant reform, but questions remain as to how this will be achieved with so little time until the state poll in November.After the vote yesterday, Mr Carroll staked his leadership on launching a royal commission into alleged corruption on the taxpayer-funded Big Build."Let me make one thing very clear: I am not Daniel Andrews But I can think of plenty of examples where they have worked."Opposition Leader Jess Wilson faced Mr Carroll in question time on Tuesday, aiming at the new premier whose leadership bid came after recent declarations of support for Ms Allan."Only last month, [Ben Carroll] said: 'I've got a young daughter at home, and I couldn't be more proud to make sure she grows up knowing I supported Jacinta Allan.'" Ms Wilson said."How can Victorians possibly believe this premier can act with integrity when governing Victoria, when he can't even be honest with his own daughter?"Victoria's election will be held on November 28.
