I thank the Member for his question. As he will be aware, the Assembly Commission agreed an approach to the decade of centenaries that requires that any Assembly Commission decisions to mark centenaries be agreed by consensus.
The Assembly Commission agreed a programme of events for the centenary. However, political consensus could not be reached on the proposal for a centenary stone when it was considered previously. While it is possible for the Assembly Commission to reconsider any proposal made to it, the issue would remain one of being able to reach a political consensus.
