International Airlines Group (IAG) chief executive Willie Walsh has declared that a British exit from the European Union would not have a "material impact" on the business, although he admitted that the possibility of a Brexit was causing uncertainty in the market.
Walsh told the BBC Radio 4 Today programme: "We have taken advice from a number of sources, we have looked at this internally, we have undertaken a risk analysis.
"Obviously there is uncertainty in the market which is weighing on people's minds. But our view is should there be a vote we don't believe it will have a material impact on our business."
This is in stark contrast to the comments made by Michael O'Leary, chief executive of Ryanair, who is actively campaigning to keep the UK in the EU. Although O’Leary agrees that Brexit would not alone cause UK air fares to rise, he said it would create years of uncertainty, which would mean less economic growth.
