The family of MLA Martina Anderson have launched a stinging attack on Sinn Féin on social media for "publicly humiliating" her.
Ms Anderson, a former IRA prisoner and current MLA for Foyle, was asked to stand aside from her role in the party last month alongside fellow MLA Karen Mullan. Both women have confirmed they will not seek re-election.
The party instigated a long investigation into election success and governance in the local comhairle ceantar last year, which culminated in the entire leadership of the group being asked to stand aside.
The news came as a "body blow" to Ms Anderson, she said, confirming the story last week.
Tonight, a Facebook post, penned by Ms Anderson's sister, with 36 others tagged in the post, many of whom are relatives of the women, called on Sinn Féin to reverse the decision.
"For the Sinn Féin’s national leadership to carry out a review in Derry and to listen to the views of some people, and then to conclude that a lifelong republican who has, we believed, made a difference in Derry .. not to forget the fact that she’s someone who has given everything that is possible to give to the struggle other than her life, should stand down for problems that were not of her making, is a far cry from the ethos of republicanism," the post reads.
"We Andersons believe if Martin Mc Guinness had been alive he would never have allowed this disgraceful tactic to be deployed.
The Facebook post went on: "This SF National leadership Review that was done in Derry resulted in a massive miscarriage of justice: they came into Derry to fix problems and left creating more.. as people are rightly disgusted at seeing a life long dedicated republican being thrown under a bus for problems that she had neither art nor part in.
Sources in Derry Sinn Féin have confirmed there has been much division within membership over the decision to remove the women, specifically Ms Anderson, who was previously seen as "untouchable" to republicans.
A Sinn Féin spokesperson said: “Sinn Féin carried out a party review in the Foyle constituency. An electoral strategy group is now overseeing preparations for the Assembly elections. Karen Mullan and Martina Anderson have indicated that they will not be running again for re-election.”
Martina Anderson has been asked to comment.
