LONDON (AP) -- Mick Jagger, Dame Judi Dench and Stephen Hawking are among dozens of celebrities and public figures in Britain who have signed a petition appealing to Scottish voters to vote to stay in the United Kingdom in a referendum in September.
The public is now being invited to sign the open letter, whose other signatories include Helena Bonham Carter, David Attenborough and Simon Cowell.
The letter tells Scottish voters taking part in the Sept. 18 referendum that the undersigned "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."
"What unites us is much greater than what divides us," the letter said. "Let's stay together."
