Donegal TD Joe McHugh said Mr Harte had left a lasting peace process legacy through his cross-community and cross-Border work.
“I went into politics after Paddy but was acutely aware when I entered Dáil Eireann of his work before me for the people of County Donegal,” said Minister McHugh.
“He also did incredible work to build bridges on this island during many dark days for our people and his lasting legacy will be the Island of Ireland Peace Park in Flanders, Belgium, which was officially opened by President McAleese in 1998.
“I want to express my deepest sympathies to his family and friends at this time. Go ndéana Dia trócaire air”.
