By Matt Chorley, Mailonline Political Editor PUBLISHED: 04:24 EST, 7 March 2014 | UPDATED: 07:23 EST, 7 March 2014 Ukip supporters and Eurosceptic Tories are making it harder to stop Scotland voting to leave the UK, Vince Cable will warn today. The Lib Dem Business Secretary will use a speech tonight to accuse right-wing parties of British ‘indulging in British nationalism and Euro-separatism’. He will tell his party’s spring conference in York that people calling for Britain to leave the EU made it harder to persuade Scots to ignore the ‘siren voices of nationalism and separatism’.
