European elections: Voters sceptical about an EU army and whether Ireland should participate
A new The Journal/Ireland Thinks poll also found that immigration is seen as the priority issue in the European elections.
Questions over EU military cooperation have long been a source of debate in the bloc.
Half of poll respondents were opposed to an EU army, with just over a third in favour.
Supporters of Fine Gael, Fianna Fáil, the Greens and Labour were in favour of Ireland's participation in an EU army.
