Jimmy Guerin, the independent councillor and brother of murdered journalist Veronica, is to stand in the General Election.
Mr Guerin has announced his intention to run in the Dublin Bay North constituency.
The Fingal councillor is not aligned to Shane Ross's Independent Alliance and, speaking to the Irish Independent last night, he said he would not be aligning himself with anyone.
Mr Guerin is a long-standing political activist and successfully contested the 2014 local elections as an independent.
"If elected, I have decided to ask those working within our community and with the homeless to nominate who they wish to replace me as a Fingal councillor," he said.
