Rolling Stones frontman Mick Jagger and Sting are among a list of more than 200 famous faces who have signed an open letter urging Scottish voters to keep Scotland as part of the United Kingdom.

An independence referendum will be held on September 18 which could see Scotland break away from the rest of the UK.

The letter, organized by historians Dan Snow and Tom Holland, gives people in Scotland the message "value the bond of citizenship."

The letter is part of the Let's Stay Together campaign which features a list of famous names that include musicians Bryan Ferry, David Gilmour, Andrew Lloyd Webber and Cliff Richard.

Other notable names to have signed the bill include Judi Dench, Helena Bonham Carter, Patrick Stewart, Stephen Hawking and Simon Cowell.
