A builder has said that he paid the former Fianna Fáil TD, Liam Lawlor, £40,000 to get a better postal address for a housing development in west Dublin.
Seamus Ross, of Menolly Homes, said the money was paid in two instalments so the houses would be listed in Lucan rather than Clondalkin.
He told the Mahon Tribunal that within days of giving Mr Lawlor a payment of £20,000, An Post wrote to him informing him that the postal address for his lands was now Lucan.
He said Mr Lawlor returned to him later in 1996, and asked him by how much had the change of address benefited him.
Mr Ross said he told him the alteration had made him an extra £2.7m.
He then agreed to give Mr Lawlor a cheque for £20,000 made out to Baltic Timber, the tribunal heard.
