The Alliance Party leader David Ford has accused Northern Ireland's four main parties of having no interest in ending segregation. Mr Ford was speaking at his party's conference in Antrim.
He said the recent Programme for Government did not address the problems of communal division.
"The four parties wish to maintain the communal carve-up which pulls this society back, but which gives them their political base," he said.
"This single issue illustrates perfectly the difference between the parties in government at Stormont and those of us in the opposition.
"Let us be quite clear, the Alliance party will not allow silence on sectarianism and on segregation."
