Deputy First Minister Martin McGuinness has said that unionist politicians must show leadership rather than playing to the lowest common dominator.
Speaking after unionist parties walked out of all-party talks, Mr McGuinness said;
"I am disappointed but not surprised that the unionist parties have decided to withdraw from an important talks process.
"Prior to the talks I asked all party leaders to issue a statement calling for calm on our streets. That did not happen.
"Unionists need to show leadership, respect the determination of the parades Commission and support the rule of law.
“Whatever the problems there can be no resort to violence.”
