A leading dissident republican organisation says it has no intention of holding "ground-breaking talks" with Sinn Féin to discuss recent violence or any other issues.

Sinn Féin Assembly member Gerry Kelly had said he will next month lead a party delegation into talks with the 32 County Sovereignty Movement, which the security forces regard as the Real IRA's political wing,

Sinn Féin said the meeting followed communication between Gerry Adams and the dissidents. Kelly said increasing violence from dissidents meant dialogue was urgently needed.

Last week, dissidents twice tried to kill security force members within 24 hours. A car bomb exploded outside a PSNI station in Derry and an under-car bomb fell off a British army major's car in Bangor, Co Down.

Last month, there was extensive rioting in nationalist areas across the North following Orange parades. Fears are growing of more violence when the loyalist Apprentice Boys march in Belfast and Derry next weekend.

However, a spokesman for the 32 County Sovereignty Movement said: "These discussions we are meant to be having with Sinn Féin in September are news to us. We've no plans to hold such talks with Gerry Kelly or any Sinn Féin delegation.

"In 2005, we sent Sinn Féin a document setting out our republican analysis and stating that Sinn Féin had abandoned Irish national sover- eignty. We still haven't re­ceived a reply. The only issue we wish to discuss with Sinn Féin is Irish national sovereignty and their five-year silence suggests they aren't interested in that."

On 30 June, Gerry Adams wrote to the Sovereignty Movement in Belfast saying Sinn Féin was the largest party in the North, its peace strategy was working and he wanted to see an end to all "armed actions".

Adams also referred to holding a meeting to discuss various issues including "how we can secure the release of political prisoners".

In its written response on 6 July to Adams' correspondence, the Sovereignty Movement noted that the Sinn Féin president had referred to republican prisoners "as political prisoners whilst others would deem them traitors".

This was a reference to Martin McGuinness calling those who murdered two British soldiers at Mass­ereene as "traitors to the island of Ireland".

The Sovereignty Movement told Adams that his "assistance" in the prisoners' ongoing battle with the regime in Maghaberry jail would be welcome.

However, it didn't agree to any meeting. On 20 July, Adams replied to the Sovereignty Movement saying a Sinn Fein delegation including Gerry Kelly, ex-IRA prisoner and Assembly member Raymond McCartney, and ex-IRA prisoner Mary Doyle, would meet the group.

A Sovereignty Movement spokesman said: "We neither requested nor agreed to attend any such meeting. For Sinn Féin to say otherwise is disingenuous."

Detectives claimed last week's attacks by Real IRA splinter group, Oglaigh na hEireann, could have caused death.

Gerry Kelly said: "Two or three people can do a lot of damage if they go undetected and have the expertise."
