Britain's former Prime Minister Gordon Brown and ex-Chancellor Alastair Darling made their last ditch attempt to woo voters for the Better Together campaign ahead of Scots going to pledge their support at polling stations on 18 September.
The latest polls by PanelBase and ICM have put the No vote in the lead by four points but is it enough to secure a victory for the union?
"We built the peace together, we built the health service together, we built the welfare state together, we will build the future together," said Brown.
"And what we have built together, by sacrificing and sharing, let no narrow nationalism split us under, ever."
