Celebrities in the United Kingdom are voicing their opinions for and against a referendum for independence for Scotland next month that, if approved, would end three centuries of union with England.
English stars Helena Bonham Carter, Simon Cowell, Sting, Judi Dench and Patrick Stewart, recently signed a petition urging Scottish residents to vote against the referendum and remain united with the rest of the U.K. At the same time, Scottish singer Susan Boyle and Scottish actor David Tennant have also voiced opposition to the split, according to The Guardian.
"We want to let you know how very much we value our bonds of citizenship with you, and to express our hope that you will vote to renew them," the letter states. "What unites us is much greater than what divides us."
British novelist J.K. Rowling, known for her Harry Potter series, wrote on her website that she made a substantial donation to the Better Together Campaign, which is against the split.
"My hesitance at embracing independence has nothing to do with lack of belief in Scotland's remarkable people or its achievements," she wrote. "The simple truth is that Scotland is subject to the same twenty-first century pressures as the rest of the world."
Meanwhile, Scottish actors Sean Connery, Gerard Butler and Brian Cox have voiced their support for the referendum and a split from the U.K.
"The Yes campaign has centered on a positive vision for Scotland," Connery said, according to the BBC. "It is rooted in inclusiveness, equality and that core democratic value that the people of Scotland are the best guardians of their own future."
Speaking at the launch for the Yes Scotland campaign that supports independence, Scottish-American actor Alan Cumming (The Good Wife) voiced his support for the referendum.
"The evidence is clear — in the past 15 years we have become stronger economically, socially, culturally and globally," he said, according to BBC. "The world is waiting for us and I know Scotland is ready."
