A Brexit could have a domino effect and ultimately lead to Denmark's exit, or Danexit, from the EU, according to a new opinion poll. Traditionally, the &quot;stay&quot; side outnumbers the &quot;Danexit&quot; side by a 2:1 margin, but now there is statistical dead heat in Denmark. A representative sample of 1,002 voters were asked in late March by the Epinion polling agency for Analyseenheden 4V, a non-partisan business consultancy, which has analysed the British referendum's ramifications for trade and politics.
