GhostWhoVotes reports a federal Nielsen poll to be published in tomorrow’s Fairfax broadsheets will show the Coalition, unchanged on last month. More to follow.

UPDATE: GhostWhoVotes further relates the primary votes are Labor 35 per cent (up one point), Coalition 43 per cent (steady) and Greens 13 per cent (down one), and the poll also shows support for gay marriage at 57 per cent and opposition at 37 per cent.

UPDATE 2: The poll finds little change in the leaders’ personal ratings. Julia Gillard is stable on both approval (54 per cent) and disapproval (39 per cent), while Tony Abbott is up two on approval to 47 per cent and down two on disapproval to 48 per cent. Gillard’s lead as preferred prime minister is 53 per cent (steady) to 40 per cent (up a point). The Coalition leads as best party to handle interest rates (47 per cent to 33 per cent) and create greater competition between the banks (46 per cent to 32 per cent). Fifty-five per cent now believe the government should serve a full term, against 42 per cent who would like a new election as soon as possible.

UPDATE 3: Essential Research also has the Coalition leading 51-49, for the third week running. Julia Gillard’s approval rating is at 43 per cent, down two on a month ago, and her disapproval up one to 38 per cent, while Tony Abbott is up a point on approval to 40 per cent and down five on disapproval to 40 per cent. Gillard’s lead as preferred prime minister has narrowed from 49-33 to 45-34. There are also questions on viewing of sport on free-to-air and pay television, presumably apropos of the anti-siphoning issue – although opinions on this are not engaged directly.
