A new ComRes poll for ITV News reveals 54 per cent want her kept out of the next UK government, and 59 per cent want the SNP as a whole to play no part in running the country . Nicola  Sturgeon today launched her party's manifesto setting out demands for as the price propping up a Labour government, promising the rest of the UK the 'hand of friendship' Polls in Scotland put the SNP on course to make huge gains north of the border, taking dozens of seats from Labour and robbing Ed Miliband of all hopes of securing an overall majority. Mr Miliband and Ms Sturgeon have ruled out a formal coalition with SNP MPs sitting in Cabinet. But they have left open the possibility of the SNP supporting a Labour government on a vote-by-vote basis, raising the prospect of Mr Miliband being forced to bow to their demands to get any legislation through. The SNP has already suggested that it will be 'entitled to vote against any bit of legislation' and 'any bit of spending' it does not agree with. It means that for Labour to pass new laws or agree to spending in England, Wales or Northern Ireland they would have to strike a deal with the SNP. With the election too close to call, and polls pointing to another hung parliament, ComRes surveyed voters to see which parties they would like to see sharing power with Labour or the Tories. The SNP got the biggest thumbs down, with 59 per cent against them playing a role in the British government and only 19 per cent in favour. Prime Minister David Cameron, pictured campaigning in Chester today, warned an SNP-Labour deal would be a 'match made in hell' for the British economy . 36 per cent of voters back the Lib Dems playing a role in the next government, with only 40 per cent against . The manifesto includes demands for extra spending, an end to benefits cuts and the scrapping of Trident . Key election promises in the SNP manifesto include: . Ms Sturgeon has made clear that in the event of a hung parliament she will take charge of talks with Labour. 'I am the leader of the party, I would lead those discussions if we're in that scenario.' she said yesterday. However, just 22 per cent of voters across the UK back the idea with 54 per cent against. It makes the SNP by far the least popular potential coalition partner. Pollsters said older British adults were the most likely to be opposed to SNP influence. An astonishing 71 per cent of those aged 65 and over want to lock Ms Sturgeon out of power, compared to 44 per cent of 18 to 24-year-olds. By contrast, 36 per cent of voters back the Lib Dems playing a role in the next government, with only 40 per cent against. Voters are more split on Ukip, with 32 per cent in favour of Nigel Farage entering a power-sharing deal, but 51 per cent opposed. Amid fears of a backlash south of the border, Ms Sturgeon claimed she was offering the 'genuine hand of friendship' to the rest of the UK. She stated: 'The SNP isn't going to Westminster to seek to bring down governments or block budgets. We're going to Westminster to build an alliance for good, positive, progressive, sensible change.' She unveiled her her £140billion  'ransom note' for Britain to drag Labour to the left, including an end to austerity, rising benefits payments and the abolition of Trident as the price Mr Miliband would have to pay for getting into Number 10. David Cameron warned any deal with the SNP to put Labour in power would force Mr Miliband to negotiate 'day by day, vote by vote, favour by favour'. This would mean 'endless bargaining and backroom deals' to keep Labour in power - even if it hit English voters in the pocket. Mr Cameron said: 'Every single decision taking the form of a ransom note – written by the SNP. 'Make no mistake, if Labour and the SNP get into power, you are going to see an alliance between a party that wants to spend, borrow and tax more…with a party that wants to spend, borrow and tax even more. 'It might be a match made in heaven for them but it is a match made in hell for the British economy.' More than half of people do not want Ukip leader Nigel Farage to play a part in the next government, but Lib Dem Nick Clegg proved the most popular with 36 per cent wanting his party back in power . Lib Dem leader Nick Clegg today made a fresh pitch to be returned to power in a second coalition. He told ITV's Lorraine: 'I know the Conservatives are playing footsie with Ukip, with this right wing alliance with Ukip, and Labour are playing footsie with the SNP. 'I'm not going to have an alliance, I'm not going to have an arrangement, nor a coalition, with Ukip or the SNP. 'The question is not is Ed Miliband or David Cameron, are one of those two going into Number 10, it's who is going to go in there alongside them. I personally think it is much better to have the Liberal Democrats around the cabinet table than Alex Salmond or Nigel Farage.'
