There is an ICM poll in tomorrow’s Sunday Telegraph. The topline figures, with changes from ICM’s most recent poll, are CON 44%(+2), LAB 31%(+1), LDEM 18%(-2). The poll was conducted between the 25th and 26th March.

It’s a very slight increase in the Conservative lead, but none of the changes are really significant. Realistically speaking, this is just another poll showing a pretty stable position. For the record though, since ICM tend to give the Conservatives some of their lower scores this actually equals their third highest rating from the company.

Still, for those getting rather bored with the voting intention figures, we can look ahead to several potentially significant events – many commentators have suggested Gordon Brown is putting great weight in the G20 summit this week to give his premiership a boost, beyond that is the budget, which could work either way, and past that we have the local and european elections, which often lead to realignments in the national opinion polls.

ICM also asked about inheritance tax, revealing an even split amongst the public. 48% agreed that increasing the inheritance tax allowance should be a priority for the next government, 48% disagreed. Amongst Conservative voters 59% said it should be a priority.

Firstly, from reading the Telegraph’s headline you might have expected to find the public slavering after swinging cuts in public spending. Only 15% of people think spending should be maintained at its present levels or cut. Look at the actual question though, it doesn’t suggest the public are ready to swallow harsh cuts.

A significant majority – 68% – did back cuts, but only 9% went for the more radical option offered of “cutting spending significantly, and hand over the financing and running of some public services to the private sector”. The vast majority of those backing spending cuts went for the option of “cut spending on administration, but make sure spending on all front-line services such as health, education and the police is maintained.” We shouldn’t be hugely surprised that 59% of people want to have their cake and eat it.

In reality politicians of all parties always promise to cut waste and administration in office and spend the money on frontline services or tax cuts, depending on their bent. Polls also invariably show that the public do indeed accept the premise that there are bucketloads of wasteful government spending that could be cut without affecting frontline services. Whether there is any political capital in promising to do so, or basing spending or taxation decisions upon an intention to do so is a different matter.

Anyway, moving onto the rest of the the figures, while the topline voting intentions figures in the Telegraph today were static, the underlying figures showed a continuing shift towards the Conservatives. Their position on issues is now similar to their position at the end of last summer when they enjoyed a much larger lead in voting intentions (The Conservatives are ahead by 20 on law and order, 24 on immigration, 7 on education, 10 on tax, 4 on unemployment (traditionally a “Labour issue”), 8 on the economy. The sole issue where Labour still lead on the NHS – and that only by an insignificant 1 point.)

Cameron’s lead as Best PM has crept up to 11 points from 8 points a month ago, his approval rating is up to plus 21. The tide still appears to be flowing in the Conservatives direction, but it isn’t reflected in the topline voting intention figures.

It is possible that this is because their is a counter-pressure in the opposite direction: people are becoming more optimistic about the economy again. We saw it very clearly in MORI’s monthly poll. The increase in optimism in YouGov’s poll is much smaller, but the trend is in the same direction. Only 14% of people expect things to get better in the next 12 months, with 54% thinking it will get worse…horrible figures, but up from last month and the month before. 2% of people think the government’s actions are working now, 13% think they will start to work soon, 28% think they will work, but not for some time.

YouGov also asked people what they thought the rate of income tax should be on incomes over £150,000. 73% of people wanted to see an increase, with 43% saying they favoured the proposed 45p rate and 30% saying they favoured a higher rate than that. This shouldn’t be much of a surprise – polls have consistently shown that the majority of the public favour a higher rate of taxation on people they perceive as very rich… getting other people to shoulder the tax burden enjoys perennial popularity.
