The motions against O'Neill and fellow Sinn Féin ministers John O'Dowd, Caoimhe Archibald and Liz Kimmins are expected to be debated as early as next Monday. However, the attempt to oust them will fail as it requires cross-community support from a majority of both unionists and nationalists in the assembly.
The row stems from a planned Orange Order march in Portadown, County Armagh. O'Neill and other senior Sinn Féin politicians have been heavily criticised by unionists for joining protests which have blocked the parade from passing along the mainly nationalist Garvaghy Road. Police are investigating the demonstrations in a "large-scale" criminal inquiry.
O'Neill has defended her actions, saying she was "proud" to stand with the residents and adding that "when the law is wrong I will stand firmly against it". In the assembly on Monday, the Sinn Féin vice-president described the planned Orange march as "unwanted, sectarian and triumphalist".
