Tipperary election candidate Marese Skehan passed away unexpectedly today.
She was campaigning to be an Independent voice for the five-seat constituency.
Gardaí say they are not treating her death as suspicious.
Ms Skehan's death means that voting will not proceed in Tipperary this Saturday as planned.
The Department Of Local Government says nominations will now have to reopen, which will postpone voting for at least a week.
