Four more years of the Belfast Agreement will result in a Sinn Fein Deputy First Minister, Democratic Unionist Party MP Mrs Iris Robinson said tonight.
She told a rally in Moneyreagh that the forthcoming Assembly election offered unionists the chance to "control" their own future.
With 56 days left before the May 29th polling date, the Strangford MP said: "The days of Ulster Unionist dominance are over. The days of whoever the Ulster Unionists put up for election being returned are long gone and with your assistance and support the days of the Ulster Unionists failing Northern Ireland are over.
"We welcome this opportunity but with opportunity comes responsibility.
"The rewards for victory are great but the price of defeat would be greater still.
"Just remember what we said five years ago and recall what the Ulster Unionists said. Unionism can not afford to trust them again.
"Four more years of the Belfast Agreement will mean Gerry Adams or Martin McGuinness as Deputy First Minister. It will mean Gerry Kelly as Policing and Justice Minister, it will mean rates massively increased and it will mean more all-Ireland Government."
Mrs Robinson said this was not merely speculation but reality.
Unionism, she claimed, would be "consigned to terminal decline" unless the DUP prevented the election of Mr David Trimble as First Minister.
She also told an audience which included Basingstoke MP Andrew Hunter that Mr Trimble's Ulster Unionists were running scared of the election because they did not want to face voters.
