A pro-union banner and the British Union flag at the Scottish borders

A new poll showed Scotland set to narrowly reject independence in a historic referendum in one week’s time, according to results by pollster YouGov on Thursday.

The survey showed the pro-union “No” campaign ahead by four points on 52 percent support, compared to 48 percent who were in favour of independence, excluding respondents who picked “don’t know”.

The result was the first time the “No” campaign had gained support in a YouGov poll since early August, when surveys began to show the pro-independence side gaining a surge of support.

A Saturday poll by YouGov showing the pro-independence side ahead for the first time electrified the campaign, prompting British Prime Minister David Cameron to cancel a parliamentary debate and travel to Scotland with rival party leaders to campaign against independence.

The survey questioned 1,268 voters between Tuesday and Thursday.

Meanwhile, Scotland’s pro-independence leader Alex Salmond said the “eyes of the world” were on a momentous referendum next week as officials reported record numbers registering to vote on breaking away from the United Kingdom.

Salmond said the September 18 vote would be “a process of national empowerment”, as new figures came out showing a record 4.3 million people had registered to vote — higher than for any previous elections in Scotland.

“Scotland is on the cusp of making history. The eyes of the world are upon Scotland,” Salmond, Scottish First Minister and the head of Scotland’s current devolved government, said in an Edinburgh speech.

“On September 18, we the people hold our destiny in our own hands.”

Alex Salmond: Yes Campaigner

British media said new figures meant 97 percent of the electorate had now registered to vote, including many 16- and 17-year-olds who are allowed to take part under referendum rules.

The vote would bring to an abrupt end a 307-year-old union between England and Scotland and create Europe newest state since the disintegration of Yugoslavia.

Many nations with separatist movements are following the campaign closely, including Spain where the government has ruled out a referendum for Catalan independence or devolution.

On Thursday hundreds of thousands of Catalan nationalist demonstrators, some waving the blue and white Scottish flag, filled the streets of Barcelona in a mass rally to demand a vote like Scotland’s.

“A ‘Yes’ vote would put a huge pressure on Madrid. Scotland is not a remote country somewhere in the world. It’s just next door,” said Carles Costa from TV3 public television in Catalonia, who was at Salmond’s press conference.
