File photo dated 17/11/2003 of Sinn Fein's Martin McGuinness who warned Sunday January 16 2005, that Northern Ireland's nationalist SDLP would be making a grave error if it signed up to a voluntary coalition without Sinn Fein. Following SDLP MP Eddie McGrady's argument that the party should consider a voluntary coalition with the Reverend Ian Paisley's Democratic Unionists, Mr McGuinness told PA his nationalist rivals should think carefully about how their community would respond.
