"I was concerned about the timing of the EU referendum, not just because of its coincidence with the Scottish election but because I felt the EU referendum needed more time for the issues to be debated. But I think the Scottish campaign is more than holding its own and will continue to do so over the remaining weeks of the campaign," Sturgeon said.
Only UK-born voters will be eligible to vote in the EU referendum to be held on June 23. Scottish voters go to the polls on May 5 to elect 129 members of the devolved administration that has control over health, education, housing and agriculture but has no influence over foreign affairs or defense issues.
The SNP currently have a majority of Members of the Scottish Parliament elected and have been in Government since 2007.
