The power-sharing Executive at Stormont has led to falling standards in Northern Ireland schools and a further deterioration of the health service, the annual conference of the DUP's Young Democrats has heard.
Mr Christopher Stalford, the chairman of the Belfast branch of the DUP's youth wing, said Sinn Féin ministers were failing to do their jobs. The conference took place on Saturday at Queen's University Belfast.
There was hissing at the mention of Sinn Féin Health Minister, Ms Bairbe de Brún.
During the 1998 referendum on the Belfast Agreement, the North's health service was promised a massive cash injection as part of a "so-called peace dividend", Mr Stalford said.
"But waiting lists are getting longer and longer. Patients are left lying on hospital trolleys in run-down and decrepit conditions. The number of people wishing to enter the nursing and general medical professions is continuing to fall, thus contributing to the disastrous cycle of decline," he said.
These problems were long-running but were not being adequately tackled by the Minister.
"Barbara Brown of IRA/Sinn Féin is the cancer which is infecting the Northern Ireland health service. Here we have a Minister, completely out of her depth, incapable and unwilling to face the challenges required of a modern health service," Mr Stalford said.
Ms de Brún had "wasted hundreds and thousands of tax-payers' money on having all literature and communications within the Department translated into Irish and English". The money could have been spent on patient care, he said.
"The people of Ulster deserve better and she should do the decent thing and resign."
Young Democrat Andrew McCreery said it was unfair that Protestant workers paid taxes which Sinn Féin ministers then spent on projects like the promotion of the Irish language. The Belfast Agreement had led to a total breakdown of law and order, with prisoners who had "run wings in the Maze prison now running community centres and local estates".
To loud applause, Mr McCreery said Sinn Féin Education Minister Mr Martin McGuinness should be put on trial at The Hague, along with Slobodan Milosevic, for war crimes.
Young Democrat Vivienne Stevenson said the DUP's annual conference last year proved the party's vibrancy. "What a stark contrast to the UUP council. Most members can't hear David Trimble because their hearing aid batteries aren't quite working properly and they can't see him for the glint of blue rinses.
"So often the DUP has been demonised as dinosaurs and yesterday's men, but we know we have a strong, united party, growing in strength each day. The media don't want the general public to find this out."
Young Democrats chairman Mr Andrew McIntyre said the DUP was the party which now spoke for unionism. "In last year's Westminster election, our party went head-to-head with the Ulster Unionist Party in 14 different constituencies and outpolled the UUP by 20,000 votes," he said.
