Labor leads coalition 51-49: Newspoll

Labor is maintaining its lead of 51 per cent to the coalition's 49 per cent in two-party preferred terms, the latest Newspoll shows.

The poll, taken for The Australian, also reveals that two out of five voters would be prepared to see a reduction in taxpayer-funded entitlements, such as family payments, as a means to repair the budget.

The post-budget poll of 1739 people taken from Thursday to Saturday gave no lift to the coalition's primary vote which is still at 41 per cent for the third consecutive survey while Labor gained one point to 37 per cent.

Newspoll found 39 per cent of voters said they would be worse off as a result of the budget while just 18 per cent believe they will be better off, with 43 per cent uncommitted.

Mr Turnbull begins the campaign with a two-point rise as the better prime minister, leading Mr Shorten by 49 per cent to 27 per cent.
