article: However, Better Together leader Alistair Darling said "there is no way back" from independence and his campaign would target undecided voters. The latest opinion polls have suggested the vote is too close to call. Both men were speaking to the BBC's Andrew Marr show. Mr Salmond said: "We're not aiming to win by one vote. We're aiming to achieve a substantial majority if we can." He added: "We tend to take the attitude that there isn't so much as a 'No' voter in Scotland, there are only deferred 'Yeses', and that's been one of the successes of our campaign." Asked if he would seek another referendum if there was a "No" vote on Thursday, the SNP leader said: "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." Mr Darling commented: "I said a year ago that this race would narrow as we got towards the wire and that is precisely what has happened. "It's not surprising.

And he argued that "about a million jobs here in Scotland depend on us being part of the UK". Mr Salmond told the Andrew Marr programme that if "Yes" won there would "cease to be a 'Yes' campaign and a 'No' campaign - there will be a Team Scotland". He said he wanted "as many voices as possible" and welcomed an indication from Secretary of State for Scotland Alistair Carmichael last month that he would join such a negotiating team. Mr Salmond said his negotiating team had "recruited specialism in a variety of fields". The first minister renewed his claim that the Bank of England would be "a shared central bank" after independence. "There will be a sustainability agreement between the governments in terms of borrowing levels and debt levels," he said. "We set that out in our proposals." The UK government has said it would not agree to a currency union with an independent Scotland, but Mr Salmond argued American economist Joseph Stiglitz had said "a shared currency is a very, very viable and common sense thing to do". Meanwhile, Mr Darling again said the pro-Union parties would deliver more powers for the Scottish Parliament if there
