A decision by DUP minister Edwin Poots to rename his Stormont department's headquarters to mark the Queen's platinum jubilee should have been referred to the Executive, officials had advised.
Mr Poots changed the name of Ballykelly House outside Limavady in Co Derry to "Jubilee House" in June following the collapse of Stormont power-sharing.
The Agriculture Minister had been told in March a referral to the Executive was "required" because the matter was "likely to be considered controversial", according to a ministerial submission seen by Belfast Live.
