The No campaign’s lead has reached a record low among people certain to vote in the Scottish independence referendum, a new poll suggests.
Support for Yes has risen to a high of 38 per cent among 733 people who will vote on September and No has held steady at 46 per cent, the same position it held as far back as November in a previous TNS poll.
Those who say they do not know how they will vote has reached a record low of 16 per cent.
Support for No among all 1,003 people polled, including those who may not vote, took a big swing upwards in July, suggesting Better Together has work to do to get its supporters to the polls and extend its lead among those certain to vote.
No rose four points to 45 per cent while Yes remained stuck on 32 per cent, a position it also held in November, among all people polled.
The survey was largely conducted during the Commonwealth Games in Glasgow, with some interviewing taking place after the August 5 televised debate between First Minister Alex Salmond and Better Together leader Alistair Darling.
The latest poll suggests that these and other recent events have had little effect on voting intentions among the 71 per cent of all adults who say they are certain to vote in the referendum, TNS said.
Tom Costley, head of TNS Scotland, said: “The fact that opinion among those certain to vote is holding steady is consistent with our previous polling, which has shown that voters on both sides are firmly committed to their views.
“With only a few weeks until the referendum, the hopes of the Yes campaign rest on winning over most of the dwindling number of undecided voters – at the end of last year, 25 per cent of those who said they were certain to vote had not made up their minds: that important pool of voters is now a third smaller.”
In all the TNS pre-referendum polling, one consistent theme is that the voters in Scotland are unhappy about the amount of information they have been given to help them make a decision.
The latest poll shows that even after months of debate and discussion and with only weeks to go until the vote, neither campaign has succeeded in giving a clear picture of what will happen after September 18.
Only 29 per cent say they have enough information about what will happen after a Yes vote and 36 per cent about what will happen after a No vote.
Mr Costley added: “While it would appear that there is still a lot of uncertainty about what will follow a Yes vote – as highlighted by the ongoing discussions about currency – the lack of clarity about a No vote suggests many are still unsure about the additional powers being offered to Scotland by the main unionist parties.”
In another poll, support for independence has increased despite growing anxiety about how a Yes vote would affect Scotland’s economy and international standing.
The latest Scottish Social Attitudes survey found support for a Yes vote increased from 36 per cent to 39 per cent during the last 12 months, while No support fell from 64 per cent to 61 per cent, excluding undecided voters.
Despite this, 38 per cent now feel an independent Scotland’s influence on the world stage would be weaker, up from a quarter in 2013.
Fears have also increased over the state of the economy under independence, with 44 per cent believing it would be worse, an increase of 10 points since last year.
The survey was carried out between May and July this year.
