Kevin Rudd is ready to secure a second double dissolution trigger later today, with the Senate to disapprove laws to launch a means test for the private health insurance rebate. The Prime Minister, previously had a trigger to summon an early election of both houses of Parliament as the Senate has twice rejected legislation to set up a emissions trading scheme in Australia - one of the centerpieces of Labor's 2007 election campaign. The laws were disapproved by the Senate in a straight indication that further measures to from a means test to the 30 per cent Medicare rebate that refunds part of the cost of private cover to families is also on the failing track later today. The Government is revealed to plan to phase out the 30 per cent rebate for singles earning more than $75,000 and for families on more than $150,000, saying the move would save more than $100 billion by 2050. The Coalition has said that the alterations will propel an exodus from private health cover, lifting up prices for remaining members and that the Prime Minister did not warn the electorate of any plans to means test the popular rebate at the last election.
