The Irish Independent quotes a whistleblower who says Deputy McGinley, when he was still a Minister last June, travelled to meet the boss of Ordnance Survey Ireland on behalf of a man from Falcarragh.
Seamus Duggan is a lifelong Fine Gael supporter. His daughter Lorraine has built a house outside Falcarragh.
She is claiming nine-feet of land which neighbour Fionan Byrne says has been in his family for four generations at least.
Mr Byrne is quoted as saying he is happy to have the matter settled in the courts.
But he is upset that his local TD would appear to have taken sides in the dispute for party political reasons saying Deputy McGinley had “no business getting involved in a matter between neighbours.”
Deputy McGinley and Mr Duggan refused to comment.
But a whistleblower said the dispute was old-fashioned political interference.
