Once undecided voters are excluded from calculations, the campaign for Scottish independence sat on 49 percent in the poll with the pro-union camp on 51 percent, according to the ICM poll results.
Those polled reported as being undecided on how to vote accounted for 17 percent, with 42 percent “No” votes and 40 percent definite “Yes” votes in the Referendum on Sept. 18.
The survey was based on telephone interviews of 1,000 people conducted between Tuesday and Thursday for The Guardian newspaper.
On Thursday, YouGov’s latest survey for The Times and Sun put the “No” campaign on 52 percent against the 48 percent “Yes” campaign, after excluding “don’t knows”.
On Sunday, the YouGov Plc’s survey for the Sunday Times put the “Yes” voters ahead of the “No” voters for the first time by 51 percent against 49 percent.
After that, the “No” campaign led the “Yes” campaign by different margins in polls by Panelbase, TNS and Survation.
About 97 percent of Scots signed up to vote in referendum as independence poll is set to be the biggest poll in Scotland’s history, with more people registered to vote than ever before.
The total number of people who have registered for next Thursday’s referendum is about 4.29 million, more than for any previous election or referendum in Scotland, according to the vote’s “chief counting officer”.
In October 2012, British Prime Minister David Cameron and Scottish First Minister Alex Salmond signed the Edinburgh Agreement, allowing Scotland to hold an independence referendum in autumn 2014 on the question of “Should Scotland be an independent country?”
