The DUP has called for an equality investigation into a decision to prevent a tree being planted on the Stormont estate to mark the platinum jubilee of Britain’s Queen Elizabeth.
The party accused Sinn Féin finance minister Conor Murphy of “intolerance and disrespect” after he declined approval for the tree planting.
It has written to the Equality Commission for Northern Ireland, which oversees adherence to equality laws in the region, asking for the decision to be investigated.
Mr Murphy, whose department has responsibility for the grounds of the Stormont estate, insisted that official policy dictated that only “international events” could be commemorated with physical structures or planting.
DUP Assembly member Joanne Bunting had sought permission to plant a tree on the estate as part of the queen’s Green Canopy project, an initiative that encourages people across the UK to “Plant a Tree for the Jubilee”.
In a written reply to East Belfast MLA Ms Bunting, seen by the PA news agency, Mr Murphy outlined the rationale for declining approval.
“Since 2016 my department’s policy on commemorative structures or planting on the grounds of the Stormont estate is to approve only those requests which commemorate international events such as World Aids Day, International Labour Day or Holocaust Memorial Day. This extends to the installation of plaques, benches or similar structures,” he said.
“I therefore cannot give approval for a tree to be planted on the estate but I wish you well in marking this event.”
The rejection is the latest in a series of recent incidents where unionists have accused Sinn Féin of preventing commemorative acts associated with their tradition.
Last year, Sinn Féin vetoed a proposal put to the Assembly Commission to place a commemorative stone in Stormont’s Parliament Buildings to mark Northern Ireland’s centenary.
The commission, made up of representatives of the main parties, has responsibility for Parliament Buildings, whereas the Department of Finance is responsible for the surrounding grounds.
