In a quietly released poll by Hanbury Strategy, with a large weighted sample of 3 884 Scots over 16, on 1st March the results were Yes 56% and No 44%.
For the male sample of 1 903, the lead was even greater at 57% to 43%.
Perhaps most striking is the huge lead for Yes among the younger voters; 81% to 19% for the 25 to 34 years olds, for example.
This is a very large sample, more than three times bigger than most and therefore significantly more reliable.
In a second wave but with a smaller weighted sample of only 1 488 on March 9th the lead is smaller but still clear-cut at 53% to 47%
