The final polls before voting opens on Thursday morning suggests the No camp are still in the lead.

A Panelbase poll reported 45% for Yes, 50% for No, and 5% either undecided or wouldn't say.

When the third category are excluded, it produces a headline figure of Yes 48% v No 52%.

That's almost completely in line with the three polls which were published on Tuesday, and reflects the average split in the four surveys which came out at the weekend.

Separately, it asked undecided voters to imagine that they were standing in the polling booth, and slightly more said they would vote No than Yes.

Adding them to the original decided totals produces a result of Yes 47%, No 53%, suggesting evidence of the "Shy No" phenomenon where voters are less supportive of independence away from pollsters or canvassers.

Panelbase, which was not working for any media outlet, interviewed 1004 adults between Monday and today.

Meanwhile, a survey conducted by Ipsos-MORI poll for STV reported 47% for Yes and 49% for No, with 4% undecided.

A YouGov poll for the Times and the Sun, which surveyed more than 3000 people, the biggest poll to date, produced a headline figure of Yes 48% and No 52% - after it excluded the 6% of voters who were undecided.

Survation also added another poll into the mix, carried out up by phone up until 9pm tonight, finding Yes 43% No 48% and Don't Know 9%.
