The Australian Labor Party has held its lead at 52-48 in the latest Guardian Essential poll despite both major parties suffering losses in their primary.

Minor parties have picked up the slack including the Greens at 12% up from 9% a week ago, and One Nation up from 6% to 7%.

The majority of voters believe the upcoming election will fall to Labor but the LNP’s Scott Morrison remains the preferred prime minister over Labor’s Bill Shorten.
