DUP prisoners request an attempt to subvert justice system - Sinn Fein
Sinn Fein has accused the DUP of trying to subvert the justice system after it asked the Prime Minister to revoke the early release licences of two republican ex-prisoners.
The Democratic Unionists have reportedly tried to have an IRA bomber linked to one of the worst attacks of the later Troubles sent back to prison after he was questioned by police about a recent murder.
The political institutions are under threat after the chief constable of the Police Service of Northern Ireland (PSNI) said the IRA still existed and some of its members were involved in shooting a man dead in Belfast last month.
Former prisoner and senior Sinn Fein member Gerry Kelly said: "The fact that Peter Robinson has asked David Cameron to revoke the licences of individual republican ex-prisoners is not acceptable.
"The DUP have quite deliberately chosen to ignore the fact that both of these men have been released unconditionally by the police.
"It is also unacceptable that these individuals have had their identities revealed in the public arena by the media. This is clearly an attempt by unionists to subvert the justice system."
Police believe the killing of Kevin McGuigan in East Belfast was a revenge attack by republican associates of former Provisionals commander Gerard "Jock" Davison, who was gunned down in May.
The revelations have created a political crisis at Stormont and prompted Democratic Unionist calls for David Cameron to intervene to suspend the devolved Assembly in Belfast and order renewed negotiations, as well as some form of independent monitoring of the IRA ceasefire.
IRA Shankill Road bomber Sean Kelly was questioned about the murder of Mr McGuigan but released without charge last month.
Kelly killed nine people when he blew up a fishmonger's in 1993. He was released from prison under the 1998 Good Friday Agreement.
Mr McGuigan, a 53-year-old father-of-nine, was gunned down in East Belfast in a suspected feud between former IRA members.
He was hit a number of times at point-blank range in front of his wife Dolores outside their home in Comber Court.
