County Enterprise Awards have been in operation for 20 years and take place annually in each of the 31 Local Enterprise Offices throughout the country.

The overall winner was Black Donkey Brewing, which produces a range of beers, with all the production taking place at Ballinlough in west Roscommon.

The other prize-winner at the awards was NCLS Crane and Lifting Services, based in Scramogue, near Strokestown.
The company was founded by 33-year-old Scott Hunter, who gave his reaction to the win to Eoghan Murphy.
