David Cameron has launched a scathing attack on a possible Labour government propped by the Scottish National Party, saying voters have "ten days to save the United Kingdom".
In an interview with The Times , the Prime Minister said that the SNP, led by Nicola Sturgeon wants the "best for Scotland and the rest of the UK can go hang".
He added: "They are not coming to Westminster to make it a success. It's not like another party that you might disagree with... it's a bunch of people who don't want the government — or indeed the country — to be a success.
"Think forward five years. Nicola Sturgeon doesn't want to go: 'That working together with Labour at Westminster thing was successful, we made a real success of the Westminster parliament and the United Kingdom is a stronger place as a result.' They want the exact opposite and Theresa May [the Home Secretary] was right to speak out as she did."
May had claimed that SNP influence over a Labour government could cause the biggest crisis since the 1936 abdication.
While conceding that SNP MPs "have every right to come to parliament" and are "equal in every other way to other MPs",Cameron said that their influence over a government led by Labour leader ED Miliband would bring "uncertainty, instability and resentment".
