Gordon Brown has warned that the Scottish nationalists want an SNP vote in the General Election to force a second referendum on independence.
The former prime minister said that SNP leader Nicola Sturgeon’s answers on the issue are ‘all evasion’.
But that her party want ‘chaos and constitutional crisis’ at Westminster to force another independence referendum.
And he warned that those casting their vote on May 7 will be deciding the future of Scotland for the next few years.
Mr Brown was speaking during a joint event with local Labour candidate and shadow foreign secretary Douglas Alexander at Elderslie Village Hall in Renfrewshire.
He said: ‘There is an SNP candidate in this constituency. She says vote SNP, get SNP MPs at Westminster and we will twist their arms and get another referendum.
‘Remember what the SNP used to say – the referendum was once in a generation, then it changed a little to once in a lifetime, then it was once every 15 years and now when you ask Ms Sturgeon about this her answers are all evasion. She cannot give a straight answer to the question.
But does not the SNP candidate in this constituency tell the truth, that what they want is an SNP vote not to deliver social justice but to deliver the chaos and constitutional crisis at Westminster to as she said force a second referendum.
‘And I say I don’t want the divisiveness, I don’t want the bitterness, I don’t want the acrimony, I don’t want the divisions between families and communities in the next few months that we had in the past few months.’
Mr Brown urged people to vote Labour to end the bedroom tax, food bank poverty, zero-hours contracts and the neglect of the NHS.
He added: ‘When you vote on May 7 remember that you are not just voting to end Tory austerity and the possibility of five more years of the bedroom tax and everything else, you’re also voting on whether you are going to allow the SNP to use your vote to try to force a second referendum on this country within a few months or after the 2016 Scottish Parliament elections.’
He also said that Labour will hold an economic summit immediately after the General Election to boost jobs, expand city deals, encourage investment and provide jobs and training for young people.
Mr Brown also urged people to be ‘proud patriotic Scots’ and back Labour’s plan for full employment in Scotland.
He said: ‘Patriotism means, yes, supporting a strong Scottish parliament, but it doesn’t mean rejecting the co-operation across the whole country that can deliver us full employment and more jobs.
‘It doesn’t mean rejecting the money that comes from the bankers’ bonus tax that will allow Scottish young people to have jobs in the future.
It doesn’t mean rejecting the co-operation on research and innovation that will replace the Linwoods of the past and the lost jobs of the present with the new high-quality jobs of the future.
‘And, yes, patriotism means a strong Scottish parliament but it doesn’t need or require us to reject the partnership that allows us to fund the pensions of this country, sharing the resources of 60 million people across the whole country, far better than pooling the resources of only five million people, to secure the best pensions imaginable.’
Monday is the last possible day to register to vote in the 2015 general election.
Anyone wishing to vote must be registered by midnight on Monday or they will not be able to.
The Electoral Commission reports that 1.7 million applications to register to vote have been made in the past five weeks, most of them online.
People can register online or visit their local town hall offices to fill in a paper form.
It is too late to post a paper registration form.
The Electoral Commission said recent applications included almost 470,000 online applications from 16 to 24-year-olds.
However, it says there may be as many as 7.5 million unregistered voters among the 45 million people eligible to vote.
More than 120,000 people applied to register online on 19 April, the most in a single day so far. There were 110,000 applications on 16 April, the day the BBC aired the debate with opposition leaders.
The majority of those website visits were made after host David Dimbleby mentioned registration at the close of the programme.
The day with the next highest number of online applications was 30 March, which was the start of the official general election campaign period and the dissolution of Parliament.
Electoral Commission chairwoman Jenny Watson said: “It takes just a few minutes to apply to register online, so do it now.
“We don’t want anyone to miss out, but if you miss the deadline on 20 April and then try to vote you will be turned away from the polling station on election day. Make sure this doesn’t happen to you.”
Politicians including Nigel Farage and Natalie Bennett have been reminding their Twitter followers to register in time.
Ed Miliband tweeted: “Your vote on 7 May can help change Britain. But you need to make sure you’re registered before midnight tonight.”
‘Don’t miss out’
Among others to urge people to sign up include actor Michael Sheen, satirist Armando Iannucci and comedian and Labour activist Eddie Izzard.
Actor Ralf Little tweeted: “Feel disillusioned? Even if you only vote to keep out the person you hate most, it all counts. Don’t miss out.”
Campaign groups have been working to persuade ethnic minorities, disabled people and young people to register.
Rachael Harrington, from Voting Counts, said too often young people did not see the link between party politics and issues affecting their lives and even those who “did not agree with the system” should register and cast a vote.
“Go and speak to your local candidates,” she urged.
“If you decide you don’t agree with them, just go and spoil your ballot or blank vote. Just staying at home makes you another statistic of people who don’t care.”
Professor Ed Fieldhouse from the University of Manchester, told BBC Radio 5Live Breakfast that young people had traditionally been among the hardest to reach, with the older and better off more likely to register.
“You do find there is a connection with social class,” he said.
“People who are unemployed or in disadvantaged economic positions are less likely to turn out to vote.”
The UK general election takes place on 7 May. Local government elections are taking place across England – excluding London – on the same day. A number of mayoral elections are also taking place.
The last general election in 2010 saw a voter turnout of 65.1% across the UK, an increase on the two previous elections in 2005 and 2001 when turnout was 61.4% and 59.4% respectively.
The 2001 election was the first time since World War Two that turnout had fallen below 70%.

Labour’s triple election winner fears referendum would cause instability not seen in Britain since second world war – and praises Ed Miliband’s convictions.
Mr Blair said Mr Cameron had put “exit on the agenda” by pledging a vote and that leaving would threaten the UK’s position as a “great global nation”.
Mr Blair, who was in his old Sedgefield constituency, also gave current Labour leader Ed Miliband his “100%” support.
Mr Cameron has pledged to renegotiate a “better deal” for the UK in Europe and to stage a referendum on the UK’s membership in 2017.
But speaking in his former constituency of Sedgefield in County Durham, Mr Blair said a referendum would be a “huge distraction” and the prospect of possible exit would leave a “pall of unpredictability hanging over the British economy”.
“And the oddest thing of all about having this referendum? The PM doesn’t really believe we should leave Europe; not even the Europe as it is today,” he said.
“This was a concession to party, a manoeuvre to access some of the UKIP vote, a sop to the rampant anti-Europe feeling of parts of the media.
“This issue, touching as it does the country’s future, is too important to be traded like this.”
Mr Blair said leaving the EU would leave Britain “diminished in the world” and take the country “out of the leadership game” globally.
