Campbell Newman’s strong, dependable leadership means Queenslanders can sleep better at night, the Liberal National Party says.

Queenslanders can sleep better at night because Premier Campbell Newman is a strong leader, the Liberal National Party says.

LNP president Bruce McIver has defended Mr Newman after a Newspoll this week showed 57 per cent of voters are dissatisfied with his leadership.

The poll also put Labor ahead of the Liberal National Party for the first time since its landslide election win in 2012.

Mr McIver described the premier as a “strong, dependable, capable leader” and said the LNP was not contemplating any change.

“Ironclad, he’s the leader going into the next election,” Mr McIver told Fairfax Radio on Wednesday.

“Queenslanders can be very confident that whatever the future holds, (with) Campbell Newman as premier we will certainly … all be able to sleep better at night knowing that he is there.”

Earlier this week, in the wake of the Newspoll, Deputy Premier Jeff Seeney said the pace of his government’s reforms may have upset voters.

“In retrospect, it is arguable that our change agenda was too much, too quick,” Mr Seeney said.

But Mr McIver defended the government’s approach.

“The urgency of those decisions was fair,” he said.

He would not be drawn on the government’s efforts to sell its agenda, and instead blamed the federal coalition government’s unpopular decisions to reduce debt.

“They’ve been a number of things that have stopped the clear message getting out about the good Queensland budget … the federal situation has been one,” he said.

Mr McIver conceded the Newman government faced a tough fight at the July 19 Stafford by-election in Brisbane’s north, four months after the LNP lost Redcliffe with a 17 per cent swing.

“We know what happened in Redcliffe. The Stafford by-election will be just as tough,” Mr McIver said.

Labor candidate Anthony Lynham, a facial surgeon at Royal Brisbane and Women’s Hospital, is considered the frontrunner, despite the LNP’s seven per cent margin.
