DUP blocks Michelle O'Neill's engagements over Drumcree

Northern Ireland's First Minister Michelle O'Neill has said Deputy First Minister Emma Little-Pengelly has "blocked" them from attending an economic summit involving Prime Minister Andy Burnham.

The Sinn Féin vice-president and Democratic Unionist Party (DUP) minister were both invited to attend the National Economic Council in Glasgow on Friday alongside other devolved leaders.

The move follows unionist anger over Sinn Féin's involvement in protests which prevented a contentious Orange Order march in Portadown from passing along the mainly nationalist Garvaghy Road.

Later the DUP leader Gavin Robinson confirmed that Little-Pengelly will not participate in joint engagements with O'Neill.

"There will be no permission granted for the First Minister to operate on a solo basis either," he said.

"Her complaints today that she's frustrated from engaging with the British Prime Minister within the sovereign United Kingdom will so be it because her law breaking must have consequences," he added.

Earlier O'Neill described the move to block the meeting as "reckless and irresponsible" and meant people in Northern Ireland "will not be represented".

"This is a reactive stunt, driven by the DUP's own internal pressures and electoral problems," she said in a statement posted online.

Little-Pengelly said the concerns arising from O'Neill's conduct and the "anger and hurt felt by many people across Northern Ireland, cannot simply be ignored or minimised".

She said the decision comes after stopping a separate planned engagement with the President of Ireland, Catherine Connolly.

"I have requested a separate meeting with the Prime Minister to ensure Northern Ireland's interests, including the urgent budgetary and funding challenges facing the Executive, continue to be represented directly," she added.

Alliance leader Naomi Long said refusing to attend or preventing others from attending the meeting with the prime minister was reckless and put party interests ahead of Northern Ireland's economic future and the needs of the public.

The Ulster Unionist Party leader Jon Burrows said the DUP's decision "punishes Northern Ireland, not Michelle O'Neill".

Party officers were expected to consider whether to withdraw the deputy first minister or cease official engagements with O'Neill, sources told the BBC's Nolan Live programme.

O'Neill and other senior Sinn Féin figures have been interviewed by police investigating last month's unnotified demonstrations in Portadown, with unionists accusing the party of acting unlawfully.

The Sinn Féin deputy leader has defended her involvement, saying it was the "right thing to do".

The prime minister revived the National Economic Council over the summer to encourage greater collaboration between the nations and regions.

In a statement posted online on Thursday , O'Neill said: "The deputy first minister has decided to block representation from here at a major political event, which would include meeting with the first ministers of Scotland and Wales, and the British prime minister.

"The Economic Forum is taking place tomorrow in Glasgow, and this reckless and irresponsible approach of Emma Little-Pengelly means the people of the north will not be represented.

"This is a reactive stunt, driven by the DUP's own internal pressures and electoral problems."
