A Midlands-Northwest MEP insists it is possible for the Irish Government to scrap the Mercosur deal.
Today, the Dáil will vote on Sinn Féin's motion calling for the trade agreement to be rejected.
Farmers strongly oppose the deal because of the amount of beef that would be allowed into the EU from South America, with thousands of farmers protesting outside the Dail yesterday to highlight their concerns.
Sinn Féin MEP Matt Carthy says it will be possible for Ireland to 'kill' the agreement.
Meanwhile, Roscommon-Galway Fianna Fáil TD Eugene Murphy says his party will support Sinn Féin's motion today.
