The parties remain gridlocked four weeks out from the July 2 election, with today's Essential Report two-party preferred outcome showing the parties at 50% each.

The Coalition's primary vote remains at 41%, while Labor's primary vote is up a point from last week to 36%. The Greens have also recovered a point to 10%, NXT is  on 4% and "others" are on 10%. A 50-50 two-party preferred outcome -- down from 51-49 to the Coalition last week -- would, on an implausible national uniform swing, deliver Labor 14 seats, leaving the Coalition in government with a small majority.
