Scots intending to vote against independence currently outnumber those voting 'Yes' by four points, according to the latest YouGov poll.

YouGov surveyed 1,268 people between 8 September to 10 September: 52% of Scots want to remain in the 307 year old union with the UK, versus 48% who are opting for independence.

This excludes those who have still not decided on how to vote.

"The 'No' campaign has moved back into the lead in Scotland's referendum campaign. This is the first time 'No' has gained ground since early August," said YouGov president Peter Kellner in a statement.

"Although 'No' is back in front, the 'Yes' campaign has held on to most of its gains since early August."

Scottish people will vote in an independence referendum on 18 September, 2014, and will be asked the straight "yes/no" question: "Should Scotland be an independent country?"

According to a Survation poll, released on 10 September, 53% of people will vote for Scotland to stay in the UK, while 47% will vote for a union break.

Another poll, released on 9 September, revealed that the respective campaigns battling to decide the future of Scotland were nearly tied.

According to the TNS poll, 39% plan to vote against independence, after support slipped massively from 45%; some 38% of Scots plan to vote for a union break - gaining ground from 32% recorded previously.

The swell in support for independence, recorded by YounGov on 7 September, marked the first time the 'Yes' vote has taken the lead since the referendum was announced.

The poll, which was conducted between 2 and 5 September, showed 51% of the 1,084 surveyed were planning to vote for independence while 49% intended to opt for staying within the union with England.
