Stormont ministers in 'north' row

There has been another row at Stormont, with First Minister Peter Robinson accusing Sinn Fein's Conor Murphy of breaching the ministerial code.

It is understood to relate to changes made to a regional development document by Mr Murphy.

"I don't think it's involves any deep-seated policy differences," said BBC NI political editor Mark Devenport.

"I'm told, of around 150 changes, many involve references to Northern Ireland being changed to the north."

Mark Devenport said Peter Robinson's perspective is "basically once a document is passed by the executive then that's it, it should be put out in that form.

"Ultimately, it could go to the courts, but I think it's more a case of symbolising the bad relations there are at the moment."

Sinn Féin MLA John O'Dowd said it was time for the first minister to stop "engaging in petty politics and get down to the business of sorting out real issues".

"It would suit Mr Robinson better if he used his time engaging in the process of intensive dialogue he committed his party to in June to sort out serious issues instead of wasting time playing petty internal unionist politics."
