A new poll has added to evidence that support for Scottish independence has risen with one month to go to the crucial referendum vote.

The YouGov poll for The Times recorded the highest level of backing for a Yes vote in its polling on the referendum question, although No support maintained a 14-point lead.

It puts support for independence at 43%, with 57% backing the Union, excluding undecided voters.

YouGov polling from earlier this month put the figures at 39% for Yes and 61% for No.

The poll of more than 1,000 people between August 12 and 15 also found an increase in the proportion of voters who believe an independent Scotland would be better off, up from 27% in June to 32%.

The proportion of people who believe the country would be worse off fell from 49% to 46% over the same period.

The latest poll shows 44% of Scots think that Westminster parties are bluffing by ruling out the Scottish Government's favoured option of a currency union between an independent Scotland and the rest of the UK, compared with 40% who believe the assertions.

YouGov found 45% back a currency union, 23% want a separate Scottish currency, 6% support the euro and 8% back a sterlingisation model.

The findings follow weekend polls that showed a similar move in support for independence.

An ICM poll of more than 1,000 people for the Scotland on Sunday newspaper put Yes backing at 45% and No at 55%, when Don't Knows were excluded.

Meanwhile, another poll by Panelbase, commissioned by the Yes campaign, reported findings of 48% for Yes and 52% for No when undecided voters were removed.
