Royal Bank of Scotland will move its registered offices to England if Scotland votes for independence from Britain in next week's referendum, the state-owned lender said on September 11, 2014. In the event of a 'Yes' vote in the historic poll on September 18, 'RBS believes it would be necessary to re-domicile the Bank's holding company and its primary rated operating entity to England', it said in a statement.
