Independence supporters gather in George Square after Scotland's First Minister Nicola Sturgeon said she would ask for permission to hold a second Scottish independence referendum | Jeff J Mitchell/Getty Images Scots don’t want another independence referendum: survey Apparent dip in support for vote could be chalked up to ‘election fatigue,’ new poll finds.

Brexit hasn't boosted pro-independence sentiment in Scotland, according to a new survey published Tuesday, Reuters reported.

Scottish First Minister Nicola Sturgeon called for a second independence referendum to be held in fall 2018 or spring 2019, after Scots voted by a wide margin to stick with the EU in last June's referendum, unlike the U.K. as a whole, which voted to leave the bloc.

According to a new Kantar poll, among 1,060 adults interviewed 26 percent said they agreed an independence referendum should be held, while 18 percent thought the vote should take place later and 46 percent of respondents thought there should be no vote at all.

Among those who said they would be certain to vote in a new referendum, 37 percent would back independence, while support for staying in the U.K. remained at 55 percent. Another 8 percent were undecided.

Criticism of the Scottish National Party's performance in areas such as health and education could be one of the reasons for the apparent weakening of pro-independence sentiment, according to the head of Kantar in Scotland Tom Costley.

"The changing economic outlook in Scotland, particularly in relation to the oil industry, may also have led to voters reassessing independence," he said. "Moreover, with [British Prime Minister] Theresa May calling a general election for June 8, there is the potential for election fatigue with the prospect of an extended referendum campaign too much for the Scottish electorate."

In Scotland's last independence referendum in 2014, Scots voted 55 percent to 45 to remain in the U.K.
