Healy and English were elected to South Tipperary County Council, for the Clonmel electoral area.[7]

Séamus Healy was the first deputy elected for South Tipperary at the 2011 general election. As a result of Healy's election to the 31st Dáil, Billy Shoer was co-opted to South Tipperary Country Council and Helena McGee was co-opted to Clonmel Borough Council.
