The party's main platform is in favour of a united
Sudan, and previously a united
Sudan and
Egypt. The basic intellectual underpinnings of the party since its general congress in late 1960s, are:
democratic pluralism politically, a
mixed economy economically, and the establishment of a
secular country towards as "the only acceptable way for peaceful coexistence in a country with different components of ethnic, tribal, religious, intellectual and cultural aspects in order to ensure the principle of that 'The sole basis of rights and duties should be based upon the Citizenship alone'." The party has long-standing relations with the
Sudan People's Liberation Movement (SPLM) with whom it signed the Peace Deal of November 1988 in
Ethiopia which was then opposed by the
National Islamic Front (NIF). It also enjoys good relationships with almost all Sudanese political groups. The last
legislative elections, December 2000, were boycotted by the party, as most of the political groups, described as unfair and rigged. Through the
National Democratic Alliance it played a major role in the opposition to the NIF regime in Sudan from 1989 until the signing of the Cairo Peace Agreement between the
NDA and the
Government of Sudan in 2005. As a consequence of its stances the DUP has suffered continuous attempts to divide and weaken it by the Sudanese security forces and the ruling party of Sudan, which seem to have failed so far. Since the signing of the Comprehensive Peace Agreement between the SPLM and the Government of Sudan, the party's position has shifted towards a more mediatory role attempting to re-align the old and new opposition parties in a comprehensive stance to tackle the broader Sudanese issues such as unity, elections and transition into democracy avoiding polarisation which it views as damaging to the long term interests of the country. It continues to view the
National Democratic Alliance as a long-term alliance that could rightly guide the political movement in
Sudan. == Electoral history ==
