Immigration Big Concern For EU Undecided: Poll

Immigration is a greater concern to undecided voters than the economy, a Sky News poll suggests. Sky Data shows that of the 29% of undecided votes, 28% are most concerned about the impact membership of the EU has on immigration - while just 15% cited the economy as the greatest concern. David Cameron, Chancellor George Osborne and the remain camp have sharply focused their campaign on the economy - a Treasury report saying that leaving the EU could cost each household £4,300.
