The campaign to keep the UK in the European Union has pulled ahead with just days to go before the vote, according to a new survey.

The UK-wide BMG telephone poll for The Herald puts support for Remain at 46% and backing for Leave on 43%, with 11% undecided or unwilling to say.

Excluding this group, 52% were in favour of staying in the EU, with 48% backing Brexit.

However a separate online survey also conducted by BMG gives Leave a double-digit lead, with 56% backing Brexit and 44% favouring Remain if Don't Knows are excluded.

The full figures were 37% Remain, 47% Leave and 16% undecided or unwilling to say.

The online poll also put support for Remain in Scotland at 52% with undecideds taken out - but this was with a sample-size of only 99.

The phone poll used a series of questions to calculate the likely voting intention of people who say they will vote but have yet to decide or do not want to say

BMG said this calculation put the Remain camp ahead on 53% compared to Leave's 47%.

Both surveys were carried out between June 10 and 15, before the fatal shooting and stabbing of Labour MP Jo Cox.

The telephone poll surveyed 1064 voters while the online survey had 1468 respondents.

The dual poll follows a series of opinion polls putting Leave ahead.

Michael Turner, research director at BMG, told the newspaper: "Our polling suggests that, although there may have been a strong shift towards a vote to Leave the EU in recent weeks, the Remain camp are still very much ahead.

"BMG currently estimates around a one in nine chance of Brexit on June 23, but this could change considerably between now and polling day."

BMG said the research suggested that Labour supporters were more than two-to-one in favour of remaining in the EU and could be the "deciding factor" in the vote.

Mr Turner added: "If we see a 'lazy Labour' effect at the polls again, that could very easily change the result."
