A leading member of the Orange Order has said the organisation's members will participate in a march in Edinburgh just days before the Scottish referendum.
Dr David Hume, director of services at the Grand Orange Lodge of Ireland, said: "We want Scotland to remain with us as part of the United Kingdom because we believe we have a better future together that way.
"We hope the campaign for an independent Scotland does not succeed. We hope the people of Scotland say No to the proposal.
"The Union would be the poorer if Scotland were to leave the Union, and Scotland would be the poorer."
