Most voters think violence against MPs 'is price worth paying' for Brexit

Research also finds voters are willing to see union 'change substantially' to get their way

A majority of voters in England, Wales and Scotland believe that violence against MPs is a "price worth paying" in order to get their way on Brexit, an academic survey has found.

The poll from Cardiff University and the University of Edinburgh asked respondents what they would be willing to see happen in order to leave or remain within the European Union.
