Michael Douglas, Sir Mick Jagger and Dame Judi Dench are among more than 200 stars who have come together to support a new drive to keep Scotland in the United Kingdom.

Bbc historian Dan Snow has put together a letter signed by hundreds of celebrities backing the 'No' campaign ahead of the Scottish referendum vote on independence in September (14).

A giant copy of the note was unveiled in London on Thursday (07Aug14), and is set to go on a tour of the rest of the United Kingdom countries so English, Welsh and Northern Irish members of the public can add their names to the star-studded list.

Snow says, "We think it is the most extraordinary list that has ever been compiled in modern British political history. It has taken my breath away."

Other celebrities to sign the list include Helena Bonham-Carter, Sir Patrick Stewart, Steve Coogan and Simon Cowell.
