Libs give farming senior cabinet role

A Liberal government would restore agriculture to a senior portfolio in cabinet.

Launching the party's agriculture policy on grower Barry Large's Miling property on Monday, state Liberal leader Colin Barnett said if elected he would make sure his door would always be open to the agriculture industry.

"The issues are many. The issues of the debate are about GM crops, about wheat marketing about water supply, salinity and it goes on and on," Mr Barnett said.
