Dublin-based Hartnett McClure PR was briefed without a pitch by the Subway's Republic of Ireland Franchise Advertising Board. The agency is charged with promoting the Subway brand in Ireland.
Subway already has 136 outlets in Ireland and aims to increase this number to 250 over the next two years. The company plans to open 2,010 outlets in UK and Ireland by 2010.
The account will be headed up by agency founders Rob Hartnett and Ian McClure.
'The current focus on healthy eating is providing an opportunity to promote Subway's healthy credentials,' said Hartnett.
Subway was founded in 1965 and has more than 29,000 outlets in over 80 countries.
The agency will work alongside three-year incumbent McKenna Townsend PR, which handles the brand's UK activity.
