Ed Miliband's personal ratings at a record low
Ed Miliband's personal ratings have fallen to their lowest level since he became Labour leader in 2010, according to a new poll.
Prime Minister David Cameron's ratings have risen to their highest since 2010, even though Labour and the Conservatives are level-pegging in the battle for voters' support.
The Ipsos Mori survey for Reuters found that 56% of those questioned were dissatisfied with Mr Miliband's performance as Labour leader, compared to 30% who were satisfied - down four points since December.
His ratings among Labour supporters had also fallen, to 46% satisfied and 44% dissatisfied. Meanwhile, some 46% of those questioned said they were satisfied with Mr Cameron's performance.
Overall, Tories and Labour each enjoyed 38% support, with Liberal Democrats on 12%. Conservatives were down three points and Labour one point since December, while Lib Dems were up one point.
The poll suggested that Britons' view of the UK's economic outlook has improved slightly, with Ipsos Mori's optimism index - those who believe the economy will get better over the next year minus those who think it will get worse - rising from minus-48 in December to minus-35 now.
Most of those questioned (62%) thought that Scotland would still be a part of the UK in five years' time, despite First Minister Alex Salmond's plans to hold an independence referendum in 2014. But half (49%) thought the UK would no longer exist in its current form in 20 years.
More than half (54%) said quitting the UK would harm Scotland's economy, against just 22% who said it would have a positive impact. Almost half (42%) said that losing Scotland would make no difference to the UK's economy and 16% said it would be beneficial, compared to 34% who said it would have a negative impact.
Ipsos Mori's head of political research, Gideon Skinner, said: "Although Conservative and Labour are tied, their leaders are moving in opposite directions. Ed Miliband's ratings are his worst since becoming Labour leader, while David Cameron's are his highest since the end of 2010.
"Meanwhile, in the long-term only a third of Britons think they will not see a break-up of the United Kingdom - but their scepticism over the impact Scottish independence would have on the economy strikes a cautionary note."
