Sinn Fein will not collude in any attempt to exclude republicans from a future justice ministry, the party's justice spokesman has said.

The DUP had suggested that a future minister should be elected by a weighted cross-community vote.
This method, however, is likely to exclude both Sinn Fein and the DUP.
Sinn Fein's Gerry Kelly told the BBC Inside Politics programme he "will not collude" in his own party's exclusion from office.
"What party could argue for its own exclusion in these circumstances?" Mr Kelly asked.
He said he and his party president, Gerry Adams, were part of a Sinn Fein delegation which met the head of the Police Service of Northern Ireland on Wednesday.
The Stormont meeting with Sir Hugh Orde came as republicans face growing pressure to support the police as part of the deal to restore devolution.
