Labour's lead over the Conservatives has remained static on three points although support for both is up at the expense of the Liberal Democrats and Ukip, according to the latest Observer/Opinium poll.
David Cameron's personal rating has fallen slightly. His net score – those of whom approve of his leadership minus those who disapprove – is now -8, with 38% approving and 46% disapproving.
Miliband's rating has fallen by four points to -24, with 24% approving and 48% disapproving.
Clegg is on -44% (16% vs 60%) and Nigel Farage is on -6% (32% vs 38%).
Opinium also asked about next month's Scottish referendum and found that 32% of those questioned believe the Commonwealth Games being held in Glasgow will affect the result. Of those 20% thought it made a yes vote more likely with 12% thinking it would more likely lead to the outcome being a no.
But most people in England and Wales want Scotland to remain in the UK with just 19% wanting them to become independent. However, when asked how the Scots themselves will vote, 27% thought they would vote to leave while 54% of voters thought they would favour staying in the union.
Opinium Research carried out an online survey of 1,979 GB adults aged 18+ from 29 July to 1 August 2014. Results have been weighted to nationally representative criteria.
