In September 1979 Síle spoke at the Liam Lynch commemoration in Fermoy, Co Cork. She called on the then Taoiseach Jack Lynch to ‘demonstrate his republicanism.’
In 1980 she accused the then British Prime Minister Margaret Thatcher of callousness, insensitivity and hypocrisy over the handling of the H-block hunger strikes.
She welcomed the election of Bobby Sands in a 1981 bi-election. She visited him in prison. She called on Nationalists to support him. Also called on Fianna Fáil to do so.
She accused Garret FitzGerald of having ‘a Free State mentality.’
Síle resigned briefly from Fianna Fáil in 1993 because of the ending of the ‘Shannon Stopover’.
She re-joined the Party in 1994 and was appointed to the opposition front bench, as spokesperson on Arts, Heritage, Gaeltacht and the Islands, by the new leader of FF – Bertie Ahern.
