DUBLIN Ireland would have to consider taking steps to assist firms exporting into Britain if its nearest neighbour and largest trade partner votes to leave the European Union, Foreign Minister Charlie Flanagan told Reuters on Wednesday. Ireland's eco**my is more vulnerable than any other in the EU if Britain opts to leave, and ministers including Flanagan have campaigned in Britain ahead of Thursday's referendum to urge Irish voters living there to vote "Remain". Irish exporters would be the first to suffer if Brexit significantly weakened the pound against the euro and Flanagan said concerns had been raised in meetings with trade bodies during the campaign.
