Steps are being taken to “resolve” issues surrounding a decision by the Orange Order to appoint a convicted wife killer to a senior role within the organisation, the UUP has said.
Stephen Fulton shot his wife Corien Fulton in the head in 1999 and was later convicted of manslaughter.
The 77-year-old was jailed for five years.
The former Royal Irish Regiment (RIR) soldier was recently appointed as worshipful district master in the Cookstown area.
North Down Alliance MLA Connie Egan has branded that decision "disgraceful".
It has also emerged that the order's new deputy district master is Mid Ulster UUP councillor Mark Glasgow. Both men are members of Cookstown LOL No 3 and were recently pictured with other newly installed officers.
Mr Glasgow declined to comment when contacted on Monday.
However, a spokesman for the UUP said the party "is aware of the situation which has arisen with regard to Cookstown District Orange Lodge.
"The party has discussed the matter with Councillor Glasgow and we understand that steps are being taken to resolve it," he said.
Alliance assembly member Connie Egan, who is the party's spokesperson on violence against women and girls, said the Orange Order must help tackle violence against women.
“Everyone in society must play a role in combatting violence against women and girls," she said.
"That includes individuals and organisations, including the orange order.
She urged the Orange Order to rethink Fulton's appointment.
“It is disgraceful it has appointed this man to a leading position and I urge those with responsibility in the order to do what they can to reverse the decision," she said.
Sinn Féin Mid Ulster MLA Linda Dillon has called for society to take a tougher stance on violence against women.
“All of society must stand against this," she said.
"There must be zero tolerance for mysognistic violence and abuse.”
The Orange Order made no comment when contacted.
A former part-time staff sergeant with the RIR, Fulton was 20 years older than his wife, who was 34, when she died.
A court heard that Fulton shot his wife in the head in the bedroom of their home at Old Rectory Heights in Cookstown.
It emerged that the murder victim had called her husband while he attended an RIR training camp in England to tell him she had met another man.
Mr Justice Gillen accepted that his actions had been substantially impaired by a classifiable mental disorder.
"I believe that it is against this background that the final straw which precipitated your taking your wife's life occurred when she removed her wedding ring in the bedroom," the judge said.
"I think that it may well have been at this moment when you decided to shoot her."
The judge added that Fulton deserved credit for his guilty plea and it was accepted he was remorseful and that there was "a measure of provocation - by your wife's threatened departure".
