This week’s YouGov results for the Sunday Times are here. Topline voting intention figures are CON 32%, LAB 35%, LDEM 7%, UKIP 15%, GRN 7%. This is a second YouGov poll in a row showing a three point lead. That could possibly be an impact from a week spent on the topic of tax avoidance, but equally it could easily just normal random error spitting out a couple of polls with above average leads in a row.

Most of the rest of the YouGov poll concentrates on that issue: HSBC, tax avoidance and evasion and party funding. Public opinion is predictably hostile towards HSBC – 80% think it’s unacceptable for banks to actively help their clients avoid tax, 75% unacceptable for them to turn a blind eye to clients doing things to avoid tax. By 71% to 15% people think that HSBC should face criminal investigation.

Blame for allowing banks to assist clients with avoiding tax is fairly evenly spread between Labour and the Conservatives. 21% think the last Labour government was more to blame, 14% that the current coalition government is more to blame, but 44% think both equally. Looking forwards, Labour have a lead on which party would do the most to tackle tax avoidance and evasion – 23% to the Conservatives’ 16%, though 50% of people said none or don’t know, suggesting little real faith in any of the parties to address the issue (compare and contrast this to the ComRes poll yesterday that showed Miliband and Cameron equal on 31% on the issue – that may be the effect of asking about leaders rather than parties, or perhaps it was because YouGov made it easier for people to say neither).

Moving onto party funding the public are critical of both the Conservative’s reliance on business funding and Labour’s reliance on Union funding. By 48% to 30% people think Labour should try and reduce Union funding, by 52% to 25% people think the Conservatives should try and reduce their business funding. More broadly only 24% of people think that donors give money purely to support a party, 68% think they do so also (19%) or mainly (49%) in the hope of getting something in return like honours or influence. Around two thirds of people would support a cap on business and trade union donations, 51% would support a cap on individual donations to political parties. There is little support though for state funding – only 19% would support taxpayer funding with 59% opposed. Even a forced choice between the current situation of a labour party getting trade union funds & a Conservative party getting business funds or a system of state funding, people would prefer the status quo by 63% to 37%.

The full tables for the YouGov/Sunday Times survey are now up here, largely covering the Labour leadership and atttitudes towards taxes on the rich.

The comparisons between Ed Miliband and David Cameron show the regular pattern we’ve seen in other polling and in the Opinium poll last night: Cameron is regarded as a stronger leader, more decisive and more likeable. He is also seen as having a clearer vision for the country and a better strategy of the economy. Where Cameron falls down, and Miliband has the advantage, is in being seen as in touch with ordinary people where Ed leads by 40% to 19%. On being trustworthy there is very little to choose between the two men.

On Ed Miliband’s leadership in particular, only 23% of people say he has made it clear what he stands for, 58% think he has not. 31% think he has been too close to the trade unions, 35% think he has not been close enough to business – surprisingly perhaps, given the often hostile attitudes polls find towards big business. While people saying Miliband is too anti-business are largely Conservative supporters, even 20% of Labour voters think Miliband has been too anti-business.

While Miliband’s ratings remain poor, he is seem as a much more appealing leader than Ed Balls or Yvetter Cooper. In both cases more people say Balls or Cooper would make them less likely to vote Labour than say they would make them more likely to vote Labour. Ed is, however, still seen as less appealing than his brother. 18% of people say they would be more likely to vote Labour with David Miliband as leader compared to only 7% who would be less likely.

Turning to taxes on the wealthy, 55% of people think that rich people are not paying enough tax and should pay more. Asked at what point higher taxes on the rich should cut in, the median point of those who gave an answer was £100,000.

However, while there is widespread support for more tax on the rich, this doesn’t necessarily translate into support for wealth taxes on the rich, as opposed to income taxes on the rich. When YouGov asked whether people thought it was fairer to tax wealth or income, 69% said income to only 22% who thought it fairer to tax wealth.

They also tested whether people generally saw the rich as making a positive or negative contribution to the country and found a fairly even split – 30% of people thought that rich people generally make a positive contribution to the country, 38% of people think they make a negative one. This goes to explain some of the other attitudes to taxes on the rich – 67% of people think that increasing taxes on the rich risks driving wealthy people abroad, but two thirds of those would support it anyway.

Tonight’s YouGov poll for the Sun has topline figures of CON 34%, LAB 42%, LDEM 9%. This is the first voting intention poll conducted wholly after the budget, though much of it was before this morning’s newspapers and the continuing media coverage we’ve had today (for the record, YouGov’s actual fieldwork times are from around about 5.30pm yesterday until around about 4pm this afternoon)

The eight point Labour lead equals the largest this year. It could be a budget knock for the Conservatives, though it is worth remembering that we also had another eight point lead earlier this week before the budget (in so much as it can be “before” a budget that had been so widely leaked), so it could be normal margin of error.

The YouGov poll has various other questions on the budget. The increase in the personal tax allowance is predictably popular, with 90% of people supporting the change. There are also solid majorities in favour of the cut in corporation tax, allowing shops to open on Sundays during the Olympics and the increaase in stamp duty on homes worth more than £2million.

Turning to the more controversial measures, 55% of people opposed the decision to cut the 50p tax rate to 45p, with 32% in support. The opposition to this measure is less strong than most of the pre-budget polling on the question – the difference is largely because polls before the budget tended to show Conservative voters opposed to the abolition of the 50p tax rate. The post-budget poll shows 60% of Tory voters in favour. Part of this might be because people are happier with a 45p compromise than abolishing the band completely, but a lot is probably Conservative supporters being more supportive of a policy when the Conservatives actually do it.

Where they haven’t done that is the least popular part of the budget, which predictably is the “granny tax”. Only 18% of people support increasing taxes paid by pensioners by phasing out the age-related tax allowance, with 64% opposed. This includes 57% of the Conservative party’s own voters and, as one might expect, 79% of people over the age of 60.

Overall just under a third of people (32%) think the budget is fair, compared to 48% who think it is unfair. To put this in context, YouGov asked the same question after last year’s budget and found 44% thought that budget was fair.

The survey also asked people whether they thought different income groups would end up paying more or less in tax as a result of the budget. 46% thought poorer people would pay less in tax, and 56% thought that the richest people in Britain will end up paying less tax. In contrast, 40% think people on average incomes will end up paying more, compared to just 23% who think they will gain and asked about “people like themselves” 21% of people think’ll end up paying less tax, 37% think they’ll end up paying more.

All this suggests the budget has not gone down well. What remains to be seen now is whether there is any real knock to voting intention once we’ve got some more polls to judge by (as ever, one should never put too much weight on one poll) and, if so, whether it lasts once the immediate negative coverage of the budget fades.
