A giant Letter to Scotland signed by more than 200 celebrities has been unveiled by Dan Snow and Ben Fogle near Tower Bridge in London.
The letter reads: "The decision on whether to leave our shared country is, of course, absolutely yours alone.
"Nevertheless, that decision will have a huge effect on all of us in the rest of the United Kingdom.
"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.
"What unites us is much greater than what divides us. Let's stay together."
