Traditional Unionist Voice (TUV) leader Jim Allister has accused the Democratic Unionist Party (DUP) of providing a "character reference" for Sinn Féin remaining at the head of Stormont's power-sharing government.

Speaking at Stormont on Monday, he reiterated his call for the DUP to withdraw Emma Little-Pengelly as deputy first minister to trigger the removal of Sinn Féin's Michelle O'Neill as first minister.

O'Neill was among senior Sinn Féin figures who joined the demonstration to block the march from passing along the Garvaghy Road.

Unionist parties have accused nationalist politicians of acting unlawfully over their involvement in the protest, which police are examining in a "large-scale criminal investigation".

O'Neill has said she chose to "stand in solidarity" with residents.

Sinn Féin councillor Catherine Nelson has also taken part in the protests.

Speaking ahead of the court challenge on Monday, she said that "legality and morality aren't always the same thing".

"Sometimes peaceful civil disobedience, which is what you're seeing on the Garvaghy Road, is how people challenge an injustice," she told the BBC's Good Morning Ulster programme.

Democratic Unionist Party (DUP) assembly member Jonathan Buckley said the Orange Order would abide by Monday's court ruling and accused Sinn Féin of disrespecting the courts and the rule of law.

He said the Portadown District did not agree with the Parades Commission's 1998 ruling that the Orange Order should not march down the road - but they had obeyed it "for 28 years".

Ulster Unionist Party (UUP) leader Jon Burrows told The Nolan Show that a resolution was needed "urgently" and "the people of Northern Ireland need leaders to lead".
