OVER the weekend, the latest polls suggest the outcome of the Scottish Independence Referendum is still too close to call.

Meanwhile, First Minister Alex Salmond, pictured right, has pledged not to bring back another referendum if Scots choose to remain in the UK.

He said one vote would be enough to win, but insisted the Yes campaign was hoping for a “substantial majority”.

According to the SNP leader, work was already under way to assemble a team of specialists to negotiate terms with the rest of the UK in the event of a vote for independence.

Several new polls show a slim lead for the “no” camp, with one suggesting the pro-independence side had a lead of eight points – the reverse of the picture in a poll commissioned by Better Together.

No leads by 50.6 per cent to 49.4 per cent, according to Panelbase for the Sunday Times and – with undecideds taken out – by 53 per cent to 47 per cent in research by Opinium for the Observer.

An ICM poll for the Sunday Telegraph put the Yes camp in front by 54 per cent to 46 per cent, although it had a smaller than usual sample size of 705.

And a Survation poll commissioned by Better Together found that 54 per cent plan to vote No while 46 per cent intend to say Yes, factoring out undecided voters.

Mr Salmond told the BBC’s Andrew Marr Show: “Harold Wilson famously (said) one vote is enough in a referendum but we’re not aiming to win by one vote, we’re aiming to achieve a substantial majority if we can.”

He added: “If you remember that previous constitutional referendum in Scotland – there was one in 1979 and then the next one was 1997. That’s what I mean by a political generation.

“In my opinion, and it is just my opinion, this is a once in a generation opportunity for Scotland.”

Asked if he could pledge not to bring back another referendum if the Yes campaign does not win on Thursday, he said: “That’s my view. My view is this is a once in a generation, perhaps even a once in a lifetime, opportunity for Scotland.”
