The push for breath-testing of all MPs before they enter NSW Parliament, doesn't have the support of the Health Minister.
NSW Opposition Leader Barry O'Farrell has backed the suggestion, which came after the resignation of Andrew Fraser for shoving a colleague on Tuesday night.
But John Della Bosca has told 2GB’s Jason Morrison, it should be about personal responsibility.
“Random breath-testing is only appropriate for certain kinds of workplaces," he said.
“My view is that you should always be sober and careful and clear-headed on the job. Especially in a job like a Parliament.”
