Independent TD Mick Wallace has said that he is prepared to go to jail for non-payment of a fine he received for breaching security at Shannon Airport.
Deputy Wallace and Deputy Clare Daly were fined €2,000 each for their anti-war protest during which they climbed a fence at Shannon to "inspect" US military aircraft.
Deputy Wallace told the Sunday Independent newspaper that he understands bench warrants have been issued over their failure to pay the fines.
If gardaí execute the warrants, the TDs could face 30-day jail terms and the prospect of Christmas in prison.
