Catalonia holds 'illegal' vote

  • Separatists in Spain's Catalan region are holding an independence referendum today despite the vote being ruled illegal by Spanish Constitutional Court.

  • Vote today is 'informal', a so-called consultation of citizens. 

  • Organisers hoping for a large turn out to reinforce symbolic nature of vote.

  • PM Rajoy on Saturday: 'we need is a return to sanity from next Monday, and let's talk within the realm of the constitution and the law'.
