Narrative:

The control position had been activated for approximately 30 mins, in anticipation of an impending holding situation. I had one aircraft (cpr X, medium large transport) holding at 140 and air carrier Y in trail was subsequently cleared to maintain 140 also. My plan was to clear other traffic traversing the sector at 130 and to descend cpr X to a lower altitude, however, I became involved in other activities and did not accomplish getting the flight to the lower altitude and sep was not maintained at the required standard.
