"If Scotland really is an equal partner in the UK [and Prime Minister] Theresa May is serious about protecting the UK, then it's time for her to turn those words into action and actually demonstrate that Scotland's voice is heard," Sturgeon said, stressing that Scotland was "highly likely" to hold a referendum before 2020 if it would not be done, as quoted by ITV.
A previous referendum on Scottish independence was held in September 2014, when 55 percent of people voted against separating from the United Kingdom.
On June 23, the United Kingdom held a referendum in which 51.9 percent of voters, or 17.4 million people, opted for the country to leave the European Union. Sturgeon has been a vocal critic of London's handling of the EU membership referendum, with the majority Scottish voters against quitting the bloc.
