ONE of Barry O'Farrell's own MPs has accused him of causing ''deliberate and disproportionate harm'' to participants in the solar bonus scheme, describing the state government's decision to slash the rate paid to them as a ''betrayal''.
As the Premier faces a backbench revolt from MPs fielding angry calls on the issue, the upper house MP Catherine Cusack has written to Mr O'Farrell criticising him for breaking an election promise and claiming cabinet was briefed with material containing ''significant errors''.
Ms Cusack, formerly the Coalition's environment spokeswoman, urges Mr O'Farrell to rethink the decision to introduce legislation to cut the rate paid to customers from 60¢ a kilowatt hour to 40¢, which was not approved by the Coalition party room.
