DUP's Peter Robinson at Stormont ahead of political talks

Mr Robinson served as first minister since 2008, but stepped aside earlier this month

The leader of the Democratic Unionist Party (DUP) will be at Stormont ahead of talks on the future of Northern Ireland's executive, after he was discharged from hospital.

Peter Robinson will brief party colleagues before talks over the political crisis, sparked by the murder of ex-IRA man Kevin McGuigan Sr.

Mr Robinson stepped aside as first minister 10 days ago.

He was discharged from hospital after being admitted as a precaution.

Mr Robinson was taken to Belfast's Royal Victoria Hospital on Saturday after suffering an adverse reaction to medication.

A DUP spokesperson said Mr Robinson "will meet party colleagues regarding the talks process" at Stormont on Monday.

Northern Ireland Secretary of State Theresa Villiers has urged politicians not to let the opportunity to secure a bright future slip away.

On Friday, the government said it had commissioned an independent assessment of paramilitary organisations in Northern Ireland.
