Murphy isn't fit to be deputy first minister
As predicted a week ago, Martin McGuinness is retiring from politics for health reasons.
The Northern Ireland deputy first minister will not be contesting the Assembly elections in March.
Once a leading member of the IRA, history will cast its judgment on his participation in the Republican movement - the bad and the good.
The departure of the 66-year-old does leave a significant gap in the Sinn Féin leadership.
Sinn Féin, in its own 'unique' way, will pick a successor to lead the party in the Assembly north of the Border.
A number of contenders' names are being mentioned, which illustrates the vacuum created by the departure of Mr McGuinness, including Conor Murphy.
Paul Quinn was murdered a decade ago by the IRA.
His family, led by his mother Breege Quinn, are still seeking justice.
When it emerged there was Provo involvement in his savage killing in south Armagh, Mr Murphy, a leading Sinn Féin figure, claimed he spoke to the IRA.
"I have spoken to the IRA in his area and I am satisfied with the assurances they gave me, very solid assurances, that they weren't involved in his death."
mr Murphy has never said to whom he spoke in the IRA and whether he brought this information to the attention of the gardaí or the PSNI, who were investigating this murder.
His lack of basic appreciation of how the fundamentals of law and order work and his failure to divulge the information available to him make Mr Murphy unfit to hold the office of deputy first minister.
It's bad enough having Gerry Adams at the helm without another friend of the Provos holding high office.
