Prime Minister Tony Abbott’s popularity has sunk to the lowest level since he became leader, with a new poll showing the Coalition government is falling out of favour with voters.

The ReachTEL poll conducted on Tuesday showed 70 per cent of people were opposed to Mr Abbott’s “captain’s pick” decision to knight the Duke of Edinburgh, Prince Phillip.

A horror week for the Coalition allowed Labor to pull ahead in the poll to lead the government on the primary vote, 40.2 to 35.5 per cent.

Labor also leads on a two-party-preferred basis, 54 to 46 per cent – a figure improved from September when Labor led 51 to 49 per cent.

The latest poll shows the majority of voters are dissatisfied with Mr Abbott, with 60 per cent rating his performance as either ‘poor’ or ‘very poor’.

Only 9.8 per cent of those polled said Mr Abbott’s performance as prime minister had been ‘very good’.

While Communications Minister Malcolm Turnbull was the most popular choice of Coalition leader with voters overall, Coalition supporters rallied behind Mr Abbott, with 39 per cent listing him at the best leader.

Forty four per cent said they wanted to see Mr Turnbull as Coalition leader, while 30 per cent nominated Foreign Minister Julie Bishop.

Only 18 per cent believed Mr Abbott was the best Coalition leader, while just 6.7 per cent wanted to see Treasurer Joe Hockey as leader.

Support for the Greens was mostly unchanged from November, up 11.3 per cent from 11.1 per cent.
