The latest opinion polls show the Scottish referendum campaign is “on a knife-edge” – with the “Yes” and “No” campaigns ahead in different surveys.
Three polls – all of which exclude undecided voters – give the “No” campaign the advantage on the final weekend of campaigning, but pro-Independence campaigners will be boosted by another which shows them ahead by a large margin.
A poll commissioned by the Better Together campaign and carried out by Survation has the “No” vote on 54% and the “Yes” camp on 46%.
Another, for The Observer newspaper, gives the “No” campaign a six point lead – 53%-47%.
Meanwhile, a poll carried out for The Sunday Times newspaper has “No” on 50.6% and “Yes” on 49.4%.
A poll for the Sunday Telegraph however showed support for independence at 54%, a nine-point swing from their last online poll, with support for the “No” campaign at 46%.
But the poll’s sample size – 705 people – means its margin of error is higher than most surveys.
Polling expert John Curtice said the poll came with “a substantial health warning”.
Sky’s Scotland Correspondent James Matthews said: “It tells us what we already know: this is going to be extremely tight, coming down to the wire, all the cliches fit.
“It really is on a knife edge and the intense campaigning over the remaining days will clearly be targeted at the undecideds, numbering something like half a million, they clearly hold the key to this referendum.”
Reacting to the latest snapshots of public opinion, Blair Jenkins, chief executive of Yes Scotland, said: “Taken in the round, the polls show that the referendum is on a knife-edge.
“There is everything to play for, and this will spur on everybody who wants and is working hard for a ‘Yes’ to redouble their efforts.
“As we say in response to all the polls, we are working flat out to ensure that we achieve a ‘Yes’ vote, because it’s the biggest opportunity the people of Scotland will ever have to build a fairer society and more prosperous economy.”
The latest polls came after First Minister Alex Salmond hit out at banks and businesses that have warned about the effects of independence.
Deutsche Bank said a “Yes” vote could be a mistake akin to those that sparked the Great Depression, while three more retailers said customers would face higher prices.
Six telecoms companies also released an open letter warning such an outcome could mean increased costs in the industry.
But Mr Salmond said in an interview with Sky News: “The people of Scotland are not going to have big government orchestrating big oil and big supermarkets to tell us we can’t run our own country.”
