Labor trusted more on energy: Newspoll

More voters trust Labor to deliver lower power prices and secure supply than the coalition, despite the Turnbull government's National Energy Guarantee policy, a Newspoll shows.

The poll shows 39 per cent trust Labor, 37 per cent back the coalition, while 24 per cent remain uncommitted to keep prices down and secure supply, the Newspoll conducted for The Australian showed.

It comes as the federal government has pushed its NEG while facing mutiny in the partyroom over coal-fired power stations, such as Liddell.

The poll was conducted between May 24-27 and covered 1591 voters across regional areas and the major cities.
