Fine Gael councillor John Naughten will win his brother Denis's seat in the general election in Roscommon-Galway, according to Ivan Yates.
The broadcaster and former agriculture minister made the prediction at a live show in Dublin last night, called Path to Power.
Denis will stand down after 27 years in the Dáil after the next election and John is hoping to take his seat.
Yates also predicts former junior minister Kevin 'Boxer' Moran, from Athlone, will win back the seat he lost in 2020 in the Longford-Westmeath constituency.
He also believes Fianna Fáil's Edel MacSharry will become a TD in Sligo-Leitrim and replace her cousin, Marc MacSharry, who is quitting politics.
