#ExportBrexit - In the 'Top 150 Born in Ireland' report, according to the Irish Exporters Association (IEA), leading companies in that sector generated around €140bn in turnover last year.

The Investec-backed study lists Ireland's largest indigenous companies by sales with building materials group CRH topping the list.

Collectively the entire list reported €139.5bn in sales with businesses in the construction and engineering sector amounting to the second-largest proportion of contributors.

Investec head of treasury Aisling Dodgson said the success of indigenous firms can sometimes be overlooked in what is becoming a more globalised market.
