NSW MPs demoted after greyhound vote

NSW Nationals MPs Katrina Hodgkinson and Chris Gulaptis have been demoted after crossing the floor over the government's Greyhound Racing Prohibition bill.

Two NSW National Party MPs who crossed the floor to vote with Labor against legislation banning greyhound racing have lost their parliamentary secretary roles.

Katrina Hodgkinson and Chris Gulaptis have been replaced by the Nationals' Adam Marshall and Bronnie Taylor.

Deputy Premier Troy Grant said Mr Marshall had been appointed Parliamentary Secretary for Northern NSW and Renewable Energy, and Ms Taylor takes on the role of Parliamentary Secretary for Southern NSW and Regional Communications.
