The SDLP is due to launch its manifesto for the upcoming Assembly election in the North later today.
The party has already vowed to defend the Good Friday Agreement against all its critics.
Yesterday, former SDLP deputy leader Seamus Mallon also made a controversial call for supporters of the agreement to transfer their votes between the SDLP and the Ulster Unionist Party.
Mr Mallon said such transfers may be necessary to prevent the anti-agreement Democratic Unionist Party from wrecking the 1998 peace deal that ended 30 years of violence in the North.
An opinion poll published yesterday predicted that the SDLP would retain its position as the dominant republican party in the North in the November 26 election.
The poll put SDLP support at 22% compared to 20% for Sinn Féin.
