The latest TNS survey reveals that 28 per cent of people who backed Labour in the 2011 Holyrood election plan to vote Yes in September's referendum, excluding those who are unsure. The figure is up from 21 per cent, on average, over the previous three months, when Labour "don't-knows" are stripped out.
TNS's findings also suggest the race is becoming closer after a period when the Yes campaign failed to eat into the No camp's lead. The poll put No on 56 per cent and Yes on 44 per cent, when the don't-knows were excluded.
