In a separate question, 46% of Scottish voters said they thought Better Together would win the referendum, with 30% believing the Yes campaign would be victorious. Twenty four percent said they don't know.

The poll also revealed that claims of negativity regarding the No campaign were reflected in the reasons behind voters' choices, with 58% of No voters saying fear for the future was more important in deciding their vote than hope. In contrast, 80% of Yes voters said they voted because they were hopeful for the future if their side won.

Seven in ten of Yes supporters based their vote more on practical consequences, with 78% saying the same from the No campaign.

Meanwhile, 24% of Yes supporters based their vote more on national identity, compared with 15% of No voters. Overall, 74% said they based their vote on practical consequences, with 19% basing theirs more on national identity.

Gideon Skinner, Head of Political Research at Ipsos MORI, said: "These results confirm the picture from other polls before polling day - the referendum looks extremely close, and although No seems to have a small lead much will depend on turnout on the day. Meanwhile there is a clear difference in the motivations for voters on the two camps - Yes voters saying they are motivated more by hope for the future if their side wins, while No voters say fear for the future if the No side loses has been more important to their vote."
