George Osborne’s ratings have plunged since his disastrous eighth Budget, according to exclusive polling carried out before and after he delivered it last week.
The full scale of the damage is revealed in Ipsos MORI research showing public hostility has grown towards the chancellor, his policies and even David Cameron.
Among the findings that will agonise Osborne’s supporters:
*Six in 10 people are dissatisfied with Osborne, including a third of Conservative supporters, compared with 46% of the public in the month before the Budget.
*Labour leader Jeremy Corbyn, who led opposition to cuts in disability benefits, has enjoyed a surge in his ratings, overtaking Cameron.
*Osborne’s Budget was the most unpopular since 2010 for the country, with majorities saying it was bad for the country and bad for the next generation.
*The biggest negative gap since 2010 has opened between the proportion of people who think government policies will improve the economy in the long-term and those who think they won’t.
*The Conservative lead over Labour has narrowed to just two points, at 36% — down three points — to 34 points, up one point.
The findings complete a week of misery for Osborne, who has been forced to downgrade his growth targets, abandon planned cuts to disability benefits, endure criticism from former welfare minister Iain Duncan Smith and look for ways to fill a  £4bn black hole in his finances.
A month before the Budget, Cameron’s satisfaction rating beat that of Corbyn by 39% to 30%. Now, however, the Labour leader is narrowly ahead, by 35% to 34%.
Before last year’s general election, marginally more people were satisfied with Osborne’s performance — 43% — than were dissatisfied — 42% — making him one of the Conservative party’s key assets.
However, after months of growing economic pessimism, the figures were 40% dissatisfied and 46% satisfied.
However, the post-Budget poll reveals that the public have turned hard against Osborne, with 60% dissatisfied and just 27% satisfied. Only 43% think his policies will improve Britain’s economy in the long-term, while 49% disagree, the worst result since Osborne moved into the Treasury in 2010.
Four out of 10 people think the Budget was bad for them — the highest proportion since 2012, the year of the so-called “omnishambles Budget”. More than half, 53%, think it was bad for the country, while just 30% thought it was good, the worst net rating for 20 years.
Osborne’s mantra that his Budget was good for the “next generation” was also a flop. Only 29% agreed, while 53% said it was bad for them, with middle-aged and older people the most critical.
