The SNP have released their manifesto and, on the first page, they’ve promised again to make Scotland independent - but with polling suggesting that Labour are heading for a landslide victory, including a majority of the seats in Scotland, could this be the end of the independence cause?  Or, paradoxically, might it end up being the best thing for the independence campaign?  Support for Scottish independence has been decoupled from support for the SNP in the polls. So might a Labour government that sticks to Conservative spending limits be just the launch pad the independence campaign needs? Joining Krishnan Guru-Murthy to discuss all this and more on The Political Fourcast are the SNP’s Mhairi Black, Scottish Labour’s Pam Duncan-Glancy and chairman of the Scottish Conservatives Craig Hoy.
